Non static Inner classes are treated as members of outer class.

To create their instances, you need to use reference of outer class.

So you have to do something like this,

OuterClass outer = new OuterClass();
InnerClass inner = outer.new InnerClass();

So, in your case,

m obj = new m();
sub1 s1 = obj.new Sub1();
