    Default Hours worked help

    Hi I cannot figure out why my program won't calculate the overtime pay correctly. Overtime is supposed to be hours worked over 40 paid at 2.5. Can someone please tell me what I am missing?
     import java.util.Scanner;
    public class If {
     
    	  public static void main(String[] args) {
    	    Scanner input = new Scanner(System.in); 
    		// TODO Auto-generated method stub
    	                float payRate;
                                       float timehours;
    		 float pay; 
     
     
    	    System.out.println("Enter payrate per hour: ");	   
                           payRate = input.nextFloat(); 			
    	    System.out.println("How many hours did you work?: "); 	    
                      timehours= input.nextFloat();	   
    	     if(timehours> 40) 
    	    {
    		pay = (float) (payRate*40+2.5*timehours); //over time pay is calculated
     
    	    }	
    	    else timehours <= 40
    	    {
    		pay= payRate*timehours; 
    	    }
     
    	    System.out.println("Your weekly pay is " + pay); 
    	  }//end of main
    	//end of class
     
    }

    Hello glacier23,

    Welcome to the Java Programming Forums.

    Firstly, I personally wouldn't call a class "If". It's best not to give a class the same name as a Java keyword.

    You have a few small errors in your code. You need to turn the else into an else if:

    import java.util.Scanner;
     
    public class If {
     
    	/**
    	 * JavaProgrammingForums.com
    	 */	
     
    	public static void main(String[] args) {
     
    		Scanner input = new Scanner(System.in);
     
                        float payRate;
                        float timehours;
                        float pay = 0;
     
            System.out.println("Enter payrate per hour: ");    
            payRate = input.nextFloat();            
            System.out.println("How many hours did you work?: ");      
            timehours= input.nextFloat();    
     
            if(timehours > 40)
            {
            pay = (float)(payRate*40+2.5*timehours); //over time pay is calculated         
            }  
            else if (timehours <= 40)
            {
            pay = payRate*timehours;
            }       
            System.out.println("Your weekly pay is " + pay);
          }//end of main
    	// end of class
     
    }

    Also, the variable 'pay' was not initialized.

    Default Re: Hours worked help

    Hi Thanks for the help with the "Else if" but for some reason it still isn't doing the calculation correctly for overtime. Say I work 45 hours at $2.00 an hour, anything over 40 hours should calculate my pay at 2.5 times the normal rate. So it is $90.00 for 40 hours but then over 40 hours it should calculate the overtime. So it is outputting 192.5 instead of 115.00. Any suggestions?

    Your calculation is wrong when the worker worked over 40 hours. The calculation should be the normal pay rate multiplied by 40 hours worked, plus 2.5 multiplied by the pay rate multiplied by the hours worked over 40 (which is timehours minus 40)

    Why? If anything for readability it should be an if and else. It is either above 40, or its not.
