Please correct my code, and using comment to explain wrong
i do half and don no how to continous.

Please answer full code with comment.

Draw the UML class diagram for Payroll class with the following descriptions. The class contains: Private field/data: Employee's name ID number Hourly pay rate Number of hours worked (should be whole number) Public constructors: A no-argument constructor that create a default payroll object. A constructor that accepts the employee's name and ID number as arguments. Public methods: Accessor methods for all data fields. Mutator methods for all data fields. A method named getGrossPay () that returns the employee's gross pay per week, which is calculated as the number of worked multiplied by the hourly pay rate. Write the Payroll class and then write a test program that demonstrates the class by creating a Payroll object. Prompt the user to input all the data for an employee. Then display the details together with the amount of gross pay earned. The sample output is as shown in Figure C1. Sample output: Enter employee name: Lily Enter employee ID: AC102922 Enter the pay rate:$ 3.50 Enter the hours worked: 40 Employee name: Lily Employee ID: AC102922 Pay Rate:$ 3.50 Hours Worked: 40 Gross Pay (a week): $ 140.00 Payroll - Employee - name : string - ID : int - Hourly-pay-rate : float - Number of hours worked : int + Payroll ( ) + Payroll (Employee name: string, ID: int, Hourly-pay-rate: float, Number of hours worked : int) + get employee-name ( ): string + get ID ( ): int + get Hourly pay-rate ( ): float + get Number of Hours worked ( ) : int + get Employee-name ( ) : string + set ID ( ): int + set Hourly pay-rate ( ): float + set Number of Hours worked ( ) : int + get Gross pay ( ): void

import java.util.Scanner;
public class Payroll
{
// u have to intialize variables only in constructor.
private String Employee_name;
private String ID;
private float hourly_pay_rate;
private int no_hours;
public Payroll()
{
Employee_name="";
ID="";
hourly_pay_rate=0;
no_hours=0;
}
public Payroll(String Employee_name,String ID)
{
this.Employee_name=Employee_name;
this.ID = ID;
}
public String getEmployee_name()
{
return Employee_name;
}
public String getID()
{
return ID;
}
public float gethourly_pay_rate()
{
return hourly_pay_rate;
}
public int getno_hours()
{
return no_hours;
}
public void setEmployee_name(String Employee_name)
{
this.Employee_name=Employee_name;
}
public void setID(String ID)
{
this.ID=ID;
}
public void sethourly_pay_rate(float hourly_pay_rate)
{

}
public void setno_hours(int no_hours)
{

System.out.println("Enter pay rate: ");
float pay_rate = (float)input.nextDouble();
pay.sethourly_pay_rate(pay_rate);
System.out.println("Enter work hours:");
int no_hours = input.nextInt();

System.out.println(" Employee Name :" + pay.getEmployee_name());
System.out.println("Employee ID :" + pay.getID());
System.out.println("Pay Rate :$" + pay.gethourly_pay_rate());
System.out.println("Hours Worked :" + pay.getno_hours());
