Question

How to call one constructor from another in Java?

Answer 1

public class Cons {

public Cons() {

// A no arguments constructor that sends default values to the largest

this(madeUpArg1Value,madeUpArg2Value,madeUpArg3Value);

}

public Cons(int arg1, int arg2) {

// An example of a partial constructor that uses the passed in arguments

// and sends a hidden default value to the largest

this(arg1,arg2, madeUpArg3Value);

}

// Largest constructor that does the work

public Cons(int arg1, int arg2, int arg3) {

this.arg1 = arg1;

this.arg2 = arg2;

this.arg3 = arg3;

}
