Java program to compare two strings

This program compare strings i.e test whether two strings are equal or not, compareTo method of String class is used to test equality of two String class objects. compareTo method is case sensitive i.e "java" and "Java" are two different strings if you use compareTo method. If you wish to compare strings but ignoring the case then use compareToIgnoreCase method.

Java programming code

import java.util.Scanner;
 
class CompareStrings
{
   public static void main(String args[])
   {
      String s1, s2;
      Scanner in = new Scanner(System.in);
 
      System.out.println("Enter the first string");
      s1 = in.nextLine();
 
      System.out.println("Enter the second string");
      s2 = in.nextLine();
 
      if ( s1.compareTo(s2) > 0 )
         System.out.println("First string is greater than second.");
      else if ( s1.compareTo(s2) < 0 )
         System.out.println("First string is smaller than second.");
      else   
         System.out.println("Both strings are equal.");
   }
}
