You'll have to download jdk7 or jre7 separately and reinstall it, since it looks like your folder was emptied out.  It just didn't delete the stub because there were demos and samples that weren't part of the uninstaller in those folders.  You can have multiple Java installations at the same time.  You just have to set the environment variables correctly for each App or process.  

The simplest thing to do is to install the version you like to use most 2nd.  It should configure the system wide environment settings last.  You can then specify the individual environment settings for the few apps that need the other version.

That doesn't sound like you're pointing to JDK.  Internet plugins is for JRE browser plugins.  I currently do not have JDK installed, just JRE, but they should normally be under /Library/Java/JavaVirtualMachines/

Platform 1.7   path : /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java  

java 1.7 has not been installed ? I mean java 1.7 jdk

That java control just shows where your internet plugin is.  The JDK should be somewhere in:

/Library/Java/JavaVirtualMachines/

It would be JAVA_HOME that Netbeans is interested in
