HowTo
Constructor Chaining
From: How do I call one constructor from another in Java?
- Use
this(args). - To call a super class, use
super(args). - Note that it must be the first call in the constructor.
The best way is from the smallest constructor to the largest.
public class Cons { public Cons() { this(madeUpArg1Value,madeUpArg2Value,madeUpArg3Value); } public Cons(int arg1, int arg2) { this(arg1,arg2, madeUpArg3Value); } public Cons(int arg1, int arg2, int arg3) { // Largest constructor that does the work this.arg1 = arg1; this.arg2 = arg2; this.arg3 = arg3; } }
