Question: To use a class, call the constructor. Below are two Java classes. The name of the first is FirstClassOOPS. It defines variables, constructors, and methods.
To use a class, call the constructor. Below are two Java classes. The name of the first is FirstClassOOPS. It defines variables, constructors, and methods. The second class is ClassClient. In ClassClient, the constructor for FirstClassOOPS is called. The constructor initializes the variable name to John Smith and age to 62. Then a method in FirstClassOOPS is used to print out the results below. My name is John Smith. My age is 62. Part I: Modify the code to make sure the print out is as follows. My name is John Smith. My age is 62. Make a screenshot of the output and include it as an attachment to the Week 4 Assignment. Also, include the program code in a text file to be evaluated. Make sure you code is commented to receive full credit (see page 45). Part II: Identify the following in the FirstClassOOPS class. Constructor(s) Mutator Methods (Set methods) Acessor Methods (Get methods) Name of methods that returns values Name the methods that do not return any values List the methods that have parameters. FirstClassOOPS public class FirstClassOOPS { // Declare Variables private String sName; private int sage; //Create default constructor public FirstClassOOPS() { sName="None"; sage = 18; } //Create a constructor public FirstClassOOPS(String name, int age) { //initialize variables sName = name; sage = age; } //Mutator Method = Method that changes the name public void setName(String name) { sName = name; } // Mutator Method = Method that changes the age public void setAge(int age) { sage = age; } //Getter Method = Method that returns the value of Name public String getName() { return sName; } //Getter Method = Method that returns the value of age public int getAge() { return sage; } //To String Method = returns the name and age public String toString() { String message = "My name is "+sName+". My age is "+sage+"."; return message; } } ClassClient below. public class ClassClient { public static void main(String[] args) { //Create a FirstClassOOPS variable with name = John Smith and age = 62 FirstClassOOPS g = new FirstClassOOPS(); String outPutString = g.toString(); System.out.println(outPutString); // The output should be // My name is John Smith. // My age is 62. // } }
