Using the == operator between objects checks for reference equality, and since you are comparing two different objects they do not equal.
Second example:
When using the == between a wrapper type (Integer, Long, etc.) and a numeric type (int, long, etc.) the wrapper type is unboxed and the equality check is done between the two primitive numeric types (I.e. between int and int). The unboxing is part of binary numeric promotion, read more here: http://docs.oracle.com/javase/specs/jls/se7/html/jls-5.html#jls-5.6.2
