Java and OOPs Assignment

Assignment:

To use a class, call the constructor. Below are two Java classes. The name of the first isFirstClassOOPS. It defines variables, constructors, and methods. The second class isClassClient. In ClassClient, the constructor for FirstClassOOPS is called. The constructor initializes the variable name to "John Smith" and age to 62. Then a method inFirstClassOOPS 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.

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+".\nMy 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.

//

}

}
