String comparison in Java

I am working with Java code in JSP and I am trying to compare strings and I am having problem with that.

I have declared two strings

s1 = "din";
s2 = "din";

However, the if (s1 == s2) never executes. Can someone help me?

Answer

You use 'equals' when you compare strings.

if(s1.equals(s2)) { true }
