In the code below:

String str1 = "Hello";
String str2 = "Hello";
if(str1 == str2)
System.out.println("str1 == str2 is true");

The output is:
str1 == str2 is true

Could you tell me why this is the output?

String literals -- i.e., occurrences in your source code of double-quoted Strings -- are pooled in the JVM. For each string literal, there will be one and only one instance of a String object used to represent it. This is described in JLS 3.10.5.
