When talking about objects (which a String is) == compares the reference. If "String" has the same reference as "String" then output: Equal. else Not Equal. [toString does not change the reference]. Consider using .equals to compare strings, as it checks character by character to see if they're indeed the same. Lets say I had: String first = "String"; String second = new String("String"); if(first == second) System.out.println("Equal"); else System.out.println("Not Equal"); The output is: Not Equal. While if I had: if(first.equals(second)) The output would be: Equal.

you are giving a conditional statement: if the string value "String" is .toString-ed and is equal to "String", then output should be Equal. else it will output Not Equal.
