Hi, I am new to this forum having a limited experience in programming(only simple C++ and basics of Java)
May some willing person help me the steps to make real applications(mobile or computer) using this programming language? `

Your request is very general, and sounds like it will need more time that anyone here has got.

Strt by reading the starting Java thread, the have alook through the Java projects for learners thread. Pick a project that interests you and try to design/code/test a solution. If/when you get stuck, come back here for specific help.
