static member class instance

[Shiva Mohan]

    
class ppp {
  ppp() {System.out.print("E");}
  static class Z {Z(){System.out.print("Z");}}
  public static void main(String args[]) {
 new ppp.Z();
  
}}

The class instance creation expression new ppp.Z() creates an instance of the static nested class E.Z.

New ppp.Z();//displaying Z

I tried writing the above coding in two lines. But I ended up with error. Like this

ppp myppp=new ppp();//---------this one displaying E
ppp.Z myZ=myppp.new Z();
Ans I got the error--------qualified new of static class. What does this error mean?

Ans also Creating the instance of Z is accepting (ok Creating instance of static variable or not creating instance that will display in static context.) Creating the instance of non static enclosing class is giving error? How? I am totally confused. Please help me.

creating an instance of the inner class requires a reference to an instance of the enclosing class.

creating an instance of the static nested class does not require an instance of the enclosing class.

Thanks for the reply wise. But I am not clear yet.

creating an instance of the static nested class does not require an instance of the enclosing class.

But here,what is that new ppp.Z()?I thought that �new ppp �is the instance of enclosing class?

[wise owen]

public class EnclosingClass {
����public static void main(String[] args) {
       EnclosingClass enclosingClass = new  EnclosingClass();
       EnclosingClass.InnerClass innerClass = enclosingClass.new InnerClass();
       EnclosingClass.StaticNestedClass staticNestedClass = new EnclosingClass.StaticNestedClass();
    } 
    class InnerClass {
       InnerClass() {
           ...
       }
    }
    static class StaticNestedClass {
       StaticNestedClass() {
             ...
       }
    }
}

Thankyou so much for your coding.That cleared my doubt.Thanks for the time.

Hello Shiva,

Your code must be like this. It ran in my end.

  
class ppp
{
 ppp()
 {
 
 System.out.println("pp");
 
 }
 
 static class Z{ Z(){System.out.println("Z");}}
 
 public static void main(String args[])
 {
new ppp();
ppp.Z myppp = new ppp.Z();
 }
 
}
