Hi,

In the java classes, is it common to write this.variable in the toString method when you are overriding it. Why is "this" written? You are able to access the variable without this.
i.e
public class test{
private String a;

@Override
      public String toString() {
return this.a;
}
}

You only really need to use the 'this' keyword if the variable is shadowed by a method or constructor parameter see :
