Question

wap to read two strings from user and display both are equal or not using equal and equalsIgnorCase() using Java program​

Answer 1

Solution:

This is written in Java -

import java.util.*;

public class Java_String{

   public static void main(String args[]){

       Scanner sc=new Scanner(System.in);

       String a,b;

       System.out.print("Enter first String: ");

       a=sc.nextLine();

       System.out.print("Enter second String: ");

       b=sc.nextLine();

       if(a.equalsIgnoreCase(b))

           System.out.println("Equal.");

       else

           System.out.println("Not equal.");

       sc.close();

   }

}

• The equalsIgnoreCase() checks whether two strings are equal or not ignoring the cases. So, strings - "ABCD" and "abcd" will be considered equal.
• However, the equals() method checks the cases too. Cases must be same otherwise it returns false while comparing two strings.

See the images for the output.

String st,st1;

System.out.println("Enter the 1st String");

st=in.next();

System.out.println("Enter the 2nd String");

st1=in.next();

if(st.equalsIgnoreCase(st1))

{

System.out.println("Both String are equal");

}

else

{

System.out.println("Both String are unequal");

}

}

}

• The method equalsIgnoreCase is used to compare 2 strings without checking the case of the Strings.
