java - Trouble with comparing integers -

i working on project cs class involves making gui game allows user play card game concentration (or memory). of code works fine, until start comparing values of each card. tell cards flip on when not have same value, remain up. have looked through code, , whenever have code:

if (card1.returnvalue() == card2.returnvalue())

it states values equal, when can see not.

here rest of code problem, appreciate help given:

correct. same.

button card1 = (button) e.getsource(); button card2 = (button) e.getsource();

since e.getsource() same card1 == card2.

java integer equals
