[Solved] How to use “this” keyword as parameter?

by


You are using this as a constructor call, e.g.

this(0,0,0);

would require a constructor with 3 integer arguments:

public class testt
{   
 int a;
 int b;
 int c;
 public testt (){
    this(0,0,0);
 }
 public testt(int a, int b, int c) {
  this.a = a;
  this.b = b;
  this.c = c;
 }
}

If you use this as a parameter, you are passing this instance of the object into a method.
