Write a method max that has two string parameters and returns the larger of the two.

In programming, it’s often necessary to compare two values and determine which one is larger.

This is particularly useful when working with strings, as they can be used to represent a wide range of data types and values.

The method “max” is a common operation in many programming languages that takes two parameters and returns the larger of the two.

In this particular case, we’re interested in a method that takes two string parameters and returns the larger of the two.

Here we will explore how to write a “max” method that works specifically with strings and discuss some of the considerations that go into implementing this functionality.

Method max that has two string parameters and returns the larger of the two using String.compareTo()
Method max that has two string parameters and returns the larger of the two using String.length()
Method max that has two string parameters and returns the larger of the two using conditional operator.

Method max that has two string parameters and returns the larger of the two using String.compareTo()

public class StringComparision {
      public static String max(String str1, String str2) {
          if (str1.compareTo(str2) > 0) {
            return str1;
          } else {
            return str2;
         }
      }
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

public class StringComparision {

public static String max(String str1, String str2) {

if (str1.compareTo(str2) > 0) {

return str1;

} else {

return str2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

This implementation uses the compareTo method of String to compare the two input strings lexicographically (i.e., by their dictionary order). If str1 is greater than str2 according to this ordering, then str1 is returned; otherwise, str2 is returned.

public static String max(String str1, String str2) {
    if (str1 == null) {
        return str2;
    } else if (str2 == null) {
        return str1;
    } else if (str1.compareTo(str2) > 0) {
        return str1;
    } else {
        return str2;
    }
}

public static String max(String str1, String str2) {

if (str1 == null) {

return str2;

} else if (str2 == null) {

return str1;

} else if (str1.compareTo(str2) > 0) {

return str1;

} else {

return str2;

}

in above implementation assumes that both input strings are non-null. If either input string is null, then the compareTo method will throw a NullPointerException. If you want to handle this case more gracefully, you could add a null check to the method:

Method max that has two string parameters and returns the larger of the two using String.length()

public class StringComparision {
    
    public String maxString(String s1, String s2){
        if(s1.length()>s2.length()){
            return s1;
        }
        else{
            return s2;
        }
    }
    
    public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      StringComparision sc=new StringComparision();
      String result=sc.maxString(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

public class StringComparision {

public String maxString(String s1, String s2){

if(s1.length()>s2.length()){

return s1;

}

else{

return s2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

StringComparision sc=new StringComparision();

String result=sc.maxString(s1,s2);

System.out.println("Largest String is: "+result);

}

here maxString method first checks the length of the two input strings s1 and s2 using the length() method of String. If s1 is longer than s2, then s1 is returned; otherwise, s2 is returned.

Largest String is: Hello kaise ho ji

1	Largest String is: Hello kaise ho ji

Method max that has two string parameters and returns the larger of the two using conditional operator

public class StringComparision {
    
    public String maxString(String s1, String s2){
       return (s1.length()>s2.length())? s1:s2;
    }
    
    public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      StringComparision sc=new StringComparision();
      String result=sc.maxString(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

public class StringComparision {

public String maxString(String s1, String s2){

return (s1.length()>s2.length())? s1:s2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

StringComparision sc=new StringComparision();

String result=sc.maxString(s1,s2);

System.out.println("Largest String is: "+result);

}

Largest String is: Hello kaise ho ji

1	Largest String is: Hello kaise ho ji

Using `Collections.max` method:

import java.util.Collections;
import java.util.List;
import java.util.Arrays;

public class StringComparision {
      public static String max(String str1, String str2) {
    List<String> list = Arrays.asList(str1, str2);
    return Collections.max(list);
    }
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.Collections;

import java.util.List;

import java.util.Arrays;

public class StringComparision {

public static String max(String str1, String str2) {

List<String> list = Arrays.asList(str1, str2);

return Collections.max(list);

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

Using `Stream.max` method:

import java.util.stream.Stream;

public class StringComparision {
      public static String max(String str1, String str2) {
        return Stream.of(str1, str2).max(String::compareTo).get();
    }
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.stream.Stream;

public class StringComparision {

public static String max(String str1, String str2) {

return Stream.of(str1, str2).max(String::compareTo).get();

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

Using `Math.max` method:

import java.util.stream.Stream;

public class StringComparision {
     import java.util.stream.Stream;

public class StringComparision {
     public static String max(String str1, String str2) {
    return (Math.max(str1.length(), str2.length()) == str1.length()) ? str1 : str2;
}
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.stream.Stream;

public class StringComparision {

import java.util.stream.Stream;

public class StringComparision {

public static String max(String str1, String str2) {

return (Math.max(str1.length(), str2.length()) == str1.length()) ? str1 : str2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

Using `if-else` statement:

import java.util.stream.Stream;

public class StringComparision {
      public static String max(String str1, String str2) {
    if (str1.compareTo(str2) > 0) {
        return str1;
    } else {
        return str2;
    }
    }
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.stream.Stream;

public class StringComparision {

public static String max(String str1, String str2) {

if (str1.compareTo(str2) > 0) {

return str1;

} else {

return str2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

Using a ternary operator with a nested `compareTo` method:

import java.util.stream.Stream;

public class StringComparision {
     public static String max(String str1, String str2) {
    return (str1.length() > str2.length()) ? str1 : (str1.compareTo(str2) > 0) ? str1 : str2;
}
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.stream.Stream;

public class StringComparision {

public static String max(String str1, String str2) {

return (str1.length() > str2.length()) ? str1 : (str1.compareTo(str2) > 0) ? str1 : str2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

Using `String.format` and a conditional operator:

import java.util.stream.Stream;

public class StringComparision {
    public static String max(String str1, String str2) {
    return String.format("%s", str1.length() > str2.length() ? str1 : str2);
}
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.stream.Stream;

public class StringComparision {

public static String max(String str1, String str2) {

return String.format("%s", str1.length() > str2.length() ? str1 : str2);

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);

}

import java.util.stream.Stream;

public class StringComparision {
  public static String max(String str1, String str2) {
    return (str1.length() > str2.length()) ? str1 : (str1.length() == str2.length()) ? str1 : str2;
}
   public static void main(String args[]) {
      String s1="Hello kaise ho ji";
      String s2="How are you";
      String result=StringComparision.max(s1,s2);
      System.out.println("Largest String is: "+result);
    }
}

import java.util.stream.Stream;

public class StringComparision {

public static String max(String str1, String str2) {

return (str1.length() > str2.length()) ? str1 : (str1.length() == str2.length()) ? str1 : str2;

}

public static void main(String args[]) {

String s1="Hello kaise ho ji";

String s2="How are you";

String result=StringComparision.max(s1,s2);

System.out.println("Largest String is: "+result);
