Do I need to have programming experience of C/C++ to learn java ?

Though it will definitely help you to learn java if you have some experience in these languages but it's not mandatory, you can learn java even without that.

Can't I use IDE's like Eclipse, Netbeans, IntelliJ IDEA etc. to learn java ?

Yes, you can definitely use, as these IDE's contains built in editor and commands to compile and run java programs, but for better learning, learn without IDE's because number of things happen automatically inside these IDE's.
