How do I call one constructor from another in Java?

public class Foo
{
    private int x;

    public Foo()
    {
        this(1);
    }

    public Foo(int x)
    {
        this.x = x;
    }
}

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;
 }
}

public class Cons {
 public static Cons newCons(int arg1,...) {
  // This function is commonly called valueOf, like Integer.valueOf(..)
  // More recently called "of", like EnumSet.of(..)
  Cons c = new Cons(...);
  c.setArg1(....);
  return c;
 }
}
