Comment on Tutorial : equals( ) Versus == in Java By Mashoud
When JVM find two string object with de same content, in order to save memory, insted of create two objects, this two objects stay referenced to the same memory location.
I mean, if you have a string "Hello" already created, when you create a new string with the same word "Hello" JVM detect that already exist this string and then did not create a new object, JVM just make a reference the two objects to the same "Hello", so S1 and S2 are "pointing" to the same place in the memory, and S1 == S2 are true
