Java – access the shadowed variable in the local class

I'm new to Java, and I'm confused in the following example

public class Test {

   int testOne(){  //member method
       int x=5;
         class inTest  // local class in member method
           {
             void inTestOne(int x){
             System.out.print("x is "+x);
         //  System.out.print("this.x is "+this.x);
           }
  }
       inTest ins=new intest(); // create an instance of inTest local class (inner class)
       ins.inTestOne(10);
       return 0;
   }
    public static void main(String[] args) {
   Test obj = new test();
   obj.testOne();
}
}

Why can't I use the "this" keyword in line 8 to access the shadowed variable in the intesone () method

Solution

Because x is not a member variable of this class; It is a local variable The keyword this can be used to access a member field of a class instead of a local variable

When a variable is masked, you do not have access to it It doesn't matter, because variables and local internal classes are all you want to change; If you want to access the shadow variable, all you need to do is rename it (or rename the shadow variable, whatever makes more sense to you)

Note: don't forget to mark the local variable as final, otherwise you can't access it even without shadow
