What will be the output of this program? (don't cheat!)

As a follow up try with i1 = 3, i2 =3

It has nothing to do with object reference vs value comparison. Would have been too easy ;)

@EclipseJavaIDE Will work for it. Its caching that support -128 to 127. Use i1.equals(i2) for value comparision

@EclipseJavaIDE Integer internal used cache -128 to 127
