Can anyone tell me what is the difference between Sun certified programmer for Java 2 Platform 1.2 and 1.4 ? I know that 1.2 has awt and io but 1.4 has not. If I want to take one of the test, which one should I take ? Actually, I am concerned about whether I need to take another upgrade test for 1.4 one because it does not provide awt and io ? Thank you in advance!
