    Can a class be defined inside an Interface .

     interface Inter{
    	class x{
    		public static void main(String[] args){
    			System.out.println("Hello World!");
    		}
    	}

    An interface can only contain constants and abstract methods.

    Yes, it's perfectly legal. The class is not an "inner" class, it is a "nested" (static) class.
    Beware that this is very uncommon and quite never used (unless in extreme/particular designs). So please, don't do this.
