[Rajani Sudhakar]

Read this piece of code carefully

if("String".replace('g','G') == "String".replace('g','G'))
System.out.println("Equal");
else
System.out.println("Not Equal");

1.the code will compile an print "Equal".
2.the code will compile an print "Not Equal".
3.the code will cause a compiler error

Correct Answer : 2.the code will compile and print "Not Equal"

But the result String formed on the lefthand side and that of the righthand side seem to be equal..

Can anyone justify the correct answer?

Thanks in advance,
rajani.

Compare the output from that code with this:

public class Test
{
    public static void main(String[] args)
    {
        if("String".replace('g','G').equals("String".replace('g','G'))) 
            System.out.println("Equal"); 
        else 
            System.out.println("Not Equal");
    }
}

Did you figure it out yet? If not, check this out, as well.
