/****************** Exercise 4 ******************* Complete Exercise 3 by creating objects to* attach to the array of references.***********************************************/public class E04_ObjectArray { E02_OverloadedConstructor[] array = new E02_OverloadedConstructor[5]; public E04_ObjectArray() { for(int i = 0; i < array.length; i++) array[i] = new E02_OverloadedConstructor(); } // An overloaded constructor that calls the // overloaded constructor from Exercise 2: public E04_ObjectArray(String s) { for(int i = 0; i < array.length; i++) array[i] = new E02_OverloadedConstructor(s); } public static void main(String args[]) { new E04_ObjectArray(); new E04_ObjectArray("Overloaded"); }}
//+M java E04_ObjectArray**Since the array is defined as a field of the class, it must be initialized in the constructor (if you try to initialize it inside main( ) you’ll get a complaint that a non-static field cannot be accessed inside a static method). I’ve gone the extra step here and created a second, overloaded constructor that initializes the array by calling the overloaded constructor from Exercise 2. The output is:
Default constructorDefault constructorDefault constructorDefault constructorDefault constructorDefault constructorOverloadedDefault constructorOverloadedDefault constructorOverloadedDefault constructorOverloadedDefault constructorOverloaded
