InnerClass call access

[Saibabaa Pragada]

Hi, I am not able call P669_MyInner04 from Line 23, In Line 4, I am able to create instance.

public class P669_MyOuter05_Ask {
    private int x = 7;

    public void makeInner() {
	P669_MyInner04 inner = new P669_MyInner04();
    }

    class P669_MyInner04 {
    }

    static class statiClass {

    }

    public static void main(String[] args) {
	P669_MyOuter05_Ask outerRef = new P669_MyOuter05_Ask();
	outerRef.makeInner();

	// Why static method cannot call regular class
	//I can do the same call at Line 7
	 P669_MyInner04 a = new P669_MyInner04();
	 
	// Here static method can call static class
	statiClass b = new statiClass();
    }
}

instance member just CANNOT be called from static context without instance of the outer class
isn't that simple
for getting the instance, you will have to create instance of outer class
and then you can access the inner class as regular inner class acts just like INSTANCE MEMBERS

AND STATIC CONTEXT CAN ACCESS STATIC FIELDS DIRECTLY

for accessing the regular inner class
we will have to first create object of P669_MyOuter05_Ask

now following code should work

 public class P669_MyOuter05_Ask {
    private int x = 7;

    public void makeInner() {
		System.out.println("building the inner class now");
	P669_MyInner04 inner = new P669_MyInner04();
    }

    class P669_MyInner04 {
		P669_MyInner04(){
			System.out.println("inner class getting instantiated");
		}
    }

    static class statiClass {

    }

    public static void main(String[] args) {
	P669_MyOuter05_Ask outerRef = new P669_MyOuter05_Ask();//reference created for accessing 
	//non static members lf the class
	outerRef.makeInner();//calls makeInner and created instance
	P669_MyInner04 a = outerRef.new P669_MyInner04();//created instance
	statiClass b = new statiClass();
    }
}
