import java.util.Scanner;
class lab13_01 { public static void main(String[] args) {class Square { private double side, area; public Square(double side) { void findSquare(double side) { void printSquare() {}
import java.util.Scanner;
class lab13_02 {
public static void main(String[] args) {

class Employee {
public Employee(String firstName, String lastName, double salary ) {

void printEmployee() {

import java.util.Scanner;
class lab13_03 {
public static void main(String[] args) {
System.out.println("Rectangle Area & Perimeter: ");
a.findPerimeter(7,8);

public Rectangle(double length, double width) {
public void setLength(double length) {

private double area, perimeter;

void printInfo() {

Challenge 2: Implement and test a class Employee. An employee has a first name (String), a last name (String) and a salary (double). A method raiseSalary and a method printEmployee will be implemented. The method raiseSalary will raise an employee salary by the amount passed to the method as an argument value.
Scanner in = new Scanner(System.in);
//Square area from the constructor
System.out.println("Calling the constructor");
Square a = new Square(5);
System.out.println("************************************");
System.out.println("Calling the methods");
System.out.println("Enter the side of the square: ");
a.findSquare(6);
a.printSquare();
}
}
this.side = side;
findSquare(side);
printSquare();
}
this.side = side;
System.out.println("This is the area of the square: " + area);
System.out.println("Calling the constructor");
}
System.out.println("***Employee Records:***\nFirst name: " + fName + "\nLast name: " + lName + "\nSalary: " + sal);
private String fName, lName;
double area = Math.pow(side, 2);
this.area = area;
}
}
Add a default and a parameterized constructor to the class Employee.
Employee john = new Employee("John", "Wick", 30000);
john.raisedSalary(2000);
john.printEmployee();
}
}
fName = firstName;
lName = lastName;
sal = salary;
}
void raisedSalary(double raiseSalary) {
double sal;
Employee john = new Employee("John", "Wick", 30000);
john.raisedSalary(2000);
john.printEmployee();
}
}
fName = firstName;
lName = lastName;
sal = salary;
}
void raisedSalary(double raiseSalary) {
double sal;
System.out.println("Calling the constructor");
class Rectangle {
this.length = length;
this.length = length;
return width;
this.width = width;
Rectangle a = new Rectangle(5,7);
System.out.println("****************************************");
System.out.println("Calling the methods");
a.setLength(5);
a.setWidth(5);
a.findSquare(7,8);
}
private double length, width;
this.width = width;
findSquare(length, width);
findPerimeter(length, width);
printInfo();
}
public double getLength() {
return length;
}
}
}
}
this.width = w;
double area = this.length * this.width;
this.area = area;
}
this.length = l;
this.width = w;
double perimeter = 2 * this.length + 2 * this.width;
this.perimeter = perimeter;
System.out.println("The area of the Rectangle is: " + this.area);
System.out.println("The perimeter of the Rectangle is: " + this.perimeter);
}
