Question

b) write the definition of the constructor in Line 1 so that the instance variables are initialized to 0. 

Write the definition of the constructor in Line 4 so that the instance variables u, v and w are initialized according to the values of the parameters a, b, and d, respectively. 

### Class Definition and Constructor Invocation Consider the definition of the following class: ```java public class CC { private int u; private int v; private double w; public CC( ) { // Constructor with no parameters } // Line 1 public CC(int a) { // Constructor with one integer parameter } // Line 2 public CC(int a, int b) { // Constructor with two integer parameters } // Line 3 public CC(int a, int b, double d) { // Constructor with two integer parameters and one double parameter } // Line 4 } ``` ### Exercises **a.** Identify the constructor invoked in each declaration: **(i)** `CC one = new CC( );` - **Line 1** **(ii)** `CC two = new CC(5, 6);` - **Line 3** **(iii)** `CC three = new CC(2, 8, 3.5);` - **Line 4**
