The use of “this” in Java

Question

If I write the following class:

public class Example {

      int j;
      int k;

      public Example(int j, int k) {
           j = j;
           k = k;
          


        

Answer 1

To avoid this, use an IDE (like Eclipse) and it will generate warnings in this case.

Also, make your fields final unless they absolutely can't be. There are a number of reasons (apart from this one) to do that.
