Method Local Inner Class Member scope access

Question

How do I access the method variable having the same name as the inner class member instance or method local variable of the inner class?

    class A{
                


        

Answer 1

I am not sure, what you actually mean, but you access a class member with the same name as a local variable with the same name like this:

public class A
{
   int a = 10;

   public void someMethodA()
   {
       int a = 5;
       this.a = 20; //change the member a from 10 to 20
      a = 30; // changes the local variable, which is only known in this method to 30
   }
}

Typically this pattern is used in constructors, to name the params the same as member variables, for example:

class Foo
{
    private int bar = 10;
    private string fooBar = 20;

    public Foo(int bar, string fooBar)
    {
        this.bar = bar;
        this.fooBar = fooBar;
    }
}
