Failed comparing two strings

[krnaveen14]

I've been trying to compare a string which is stored in two diffrent variables(but the content is same). I get the two same inputs from user..

package switchcasepgm;
import java.util.Scanner;

public class stringcomp {
    public static void main(String[] args)
    {
        Scanner getinp=new Scanner(System.in);
        System.out.println();
        String sdr = getinp.nextLine();
        System.out.println();
        String rds = getinp.nextLine();
if(sdr==rds)
{
    System.out.println("succ");
}
else
{
    System.out.println("fail");
}

}
}

But the output always returns the else statement.. here's the output..

yes

yes
fail

even i tried for if(sdr=="yes"), it to returns only the else statement.. I've tried for many possibilites, but not get it..

You compare srtings with the method equals() in the String class
sdr.equals(rds). Equals would check whether the objects are the same, while == checks their references

thank you.. and from this, i tried out the sdr.equals("yes"), and it works too.. thanks for the reply..
