    Question static context

    Hello

    public class test
    {
    	public static void main(String[] args)
    	{
    		fail f = new fail();
    	}
     
    	class fail
    	{
     
    	}
    }

    I got this: non-static variable this cannot be referenced from a static context

    public class test
    {
    	public static void main(String[] args)
    	{
    		test yeah = new test();
    	}
    }

    It works


    Both variables aren't static. Why in the first case it doesn't work?

    Thank you very much

    Default Re: static context

    You must declare a nested class static if you try to instantiate it from a static context (eg main). Inner classes (non-static nested classes) have access to the variables in the enclosing class...the way in which you are trying to instantiate the inner class there is no enclosing object of the outer class.
