    Step 1: just set the JDK to Java 7 and make sure that the project is not set to Java 6 compatibility, then check if something breaks. If not, try to run. – Gimby Aug 12 '15 at 07:19

    Just in case the mild sarcasm is lost in that comment: What I'm saying is that at this point you don't even know you need to migrate anything so you're asking about something which may be entirely a non-issue. Try before you ask. – Gimby Aug 12 '15 at 07:22
  • Gimby, just want to tel you that. I will follow the steps as like below:
    1. Uninstall Jav6 from system 2. Install Java 7 and 3. Point to Java 7. Is it correct?     – user3371058 Aug 12 '15 at 07:26

Upgrading code requires almost nothing, as Java 7 is backwards compatible with Java 6 except for a few things, mostly behavioral and in the standard library. And as said here, it should mostly just work:

What do I need to do?

Option 1 – “Just run”

Upgrading your eclipse project has been asked and answered several times, like here.
