Compare substring with string?

Why isn't it working?

Java Code:

                                 if ((line.substring(i,i+2)) == "go")
                                                break;

I printed this to check if substring works fine, used this:

Java Code:

   System.out.println(line.substring(i,i+2) + " : "+ length);

So, output:



Er : 1



ra : 2



ag : 3



go : 4



on : 5



n' : 6



'> : 7

Line:



String line = "Eragon'>";

Shouldn't it break loop after printing "go : 4"?



line.substring(i,i+2) prints go here. But if doesn't work.



What is wrong?
