Should I remember all the menthods of classes?

[Fei Ng]

Like collections class and interface.?
like the java.awt classes?
I/O classes?
Like the wrapper classes and the java.lang classes?
etc .. the Math class and String class and StringBuffer class.

No, you don't have to know all the methods of all the classes, but it helps to know the common ones, especially in heavily used classes like Thread, String and StringBuffer. Use the published objectives as a guide.
