How to update Jre and Jdk
I am trying the try with resource statement:

        try(ObjectOutputStream oos=new ObjectOutputStream(new FileOutputStream(defaultFile)))
    	{
    		;
    	}
    	catch(IOException e)
    	{
    		;
    	}

But I get syntax error, which makes me think that I need the newest version of Java.
So I have downloaded the latest Jre and Jdk from Oracle site, but I don't know how to effectively substitute the new Jre and Jdk with the older ones.
I have tried from eclipse windows->preferences->installed JREs, the is the option "search".But If I try searching in the directory where I have Jre and Jdk files, it says that no valid Jre was found.
How to effectively update Jre and Jdk?
PS:I am on ubuntu 10.10
