but i can't do in java.
Out of curiosity, if that's the case, how did you pass the
SCJP?
Just passing an exam doesn't give you a lot of experience. You need to practice your Java skills, maybe on projects of your own or some open-source projects. There are probably a number of APIs that you need to be aware of, Servlets/JSP,
JDBC, maybe Swing, depending on what kind of software you'd like to work on (not sure if those are covered by your exam). Also build tools (
Ant, Eclipse, NetBeans, IntelliJ) and 3rd party libraries (
Struts, log4j, familiarity with XML technologies etc.) Good luck.
