Find the actual scope of a variable declared multiple times in Java

Question

I have a program that is like this :

class A {
String abc;

public void f1(){
    String abc = 'test';
    System.out.println(abc);   
    if (true){
          String abc = 'something else';
          System.out.println(abc);   
    }
}

public void f2(){
    String abc = 'something else';
    System.out.println(abc);   
}

}

Now as we can see here we have three different variable declarations of the string abc. I wish to make a dependency matrix which will have slots for all the three declarations , that point to different memory locations. Is there any way I could get the declarations for each variable name along with the parent class or method it belongs to? Or more precisely , can I get the scope of a variable ,I.E whether it is a class variable or a variable that belongs to a method ?

I have tried using JavaParser but couldn’t find a suitable method that would do the same. Kindly help me out. Thanks a lot!!
