Answer 1

class Employee {
	private String name;
	private double salary;
	private int hours;
	private int leaveDays;


	public Employee() {


	}


	public Employee(String name) {
		this.name = name;
	}


	public Employee(String name, double salary, int hours, int leaveDays) {
		this.name = name;
		this.salary = salary;
		this.hours = hours;
		this.leaveDays = leaveDays;
	}


	public void setName(String name) {
		this.name = name;
	}


	public String getName() {
