Nonstatic nested class execution doubt

[Shiva Mohan]

   
class ppp {
  private static int counter;
  public static int getCounter(){  return counter++;}
  private static int innerCounter;
  public static int getInnerCounter(){return innerCounter++;}
  private String name;
  ppp() {name = "A" + getCounter();
  
  }
  class B {
    private String name;
    B() {
      name = "B" + getInnerCounter();
      
      System.out.print(ppp.this.name +this.name);//or name // 1
  }}
  static void m1() {new ppp().new B();}  // 2
   void m2() {this.new B();}     // 3
  static void m3() {new ppp().new B();}          // 4
  public static void main(String[] args) {
      ppp myA=new ppp();
    m1(); myA.m2(); m3();
}}
 

Output is A1B0A0B1A2B2 .Starting itself I am getting trouble that getting value is A0.
How the starting value A1 is coming. It might end up like silly doubt. But I couldn�t figure it out.

I figured it out. Ppp() is called first time by this ppp myA=new ppp();
Then calling m1()���
Thanks.

Hi Shiva,
I could understand the output A1B0 ( the first part of answer) . Could you please explain the remaining part of the answer ?I also have one more doubt.
new ppp().new B() ( //line 4 ) . Will this create an instance of B alone or ppp too ?

Thanks in advance

new ppp().new B() ( //line 4 ) . Will this create an instance of B alone or ppp too ?

Class B is an inner class. When you create an instance of B, it requires an instance of Outer class here ppp, so both objects will be created. writing simply new B() in main method is wrong.
