help needed on Inner classes program

[Naveen Megharaj]

The code goes like this

  


public class A1 {

    public A1() {
    }
    
    private String runNow() {
        return "High";
    }
    
    static class B1 extends A1 {
        public String runNow() {
            return "Low";
        }
    }
    
    public static void main(String[] args) {
        A1[] a1=new B1[] {new B1(),new C1()}; 
        for(A1 aa:a1)
            System.out.println(aa.runNow() + "");
        B1 b1=new C1();
        System.out.println(b1.runNow());

    }
    
}
class C1 extends A1.B1 {
    public String runNOw() {
        return "Out";
        
    }
}   
  

Above program produces the output as:
High
High
Low

But i was expecting it as:
High
High
Out

Since class C extends inner class -class B and overrides the 'runNOw()' method and hence a call to 'runNow() ' method on reference variable of type "B1" which points to an object of type C1 should produce the output as "Out". But its not doing so.....can anybody explain why.....?

This question is from my ExamLab SCJP exam simulator. When posting questions again, please QuoteYourSources.

You are getting that output because Java is case-sensitive. In other words runNow() is not equivalent for runNOw()

Hint: ExamLab has a "Copy Program" button which can be used to copy the entire program in to the clipboard.

Precede the runNOw method with the @Override annotation and see what happens when you try to compile the class. And Devaka Cooray is correct about quoting sources.
