Java Student Project - Time Worked

Java Student Project

TimeWorked

Ability Level:

Beginner

Estimated Time:

40 minutes

Objectives:

To learn how to use variables and constants.
To learn about the int, floating-point, and char data types.
To learn how to write arithmetic statements.
To learn about the modulus operator.

Materials & Resources:

Java Software
Textbook

Overview:

Write a program that declares a minutes variable which will be the identifier for the minutes worked on a job. Assign a value ( 256 ) to this variable. Use the modulus operator to calculate the the hours and minutes. Display the value in hours and minutes such as 4 hours and 29 minutes. Display explanatory text with the values.

Instructions:

Use the following template to help you get started:

public class timeWorked
{
   public static void main(String args[])
    {
       System.out.println("Program Time Worked");
       .....[code here]
     }
   }

Hints:

Some important points to keep in mind in doing this project:

Variable names usually begin with lowercase letters to distinguish variable names from class names.
You can declare variables at any point within a method prior to their first use. It is common practice to declare variables first and place method calls second.
You can use modulus ( % ) only with integers. All other operators can be used with floating-point data.
Modulus division returns the remainder of the integer division problem.
An operand is simply any value used in an arithmetic or logical operation.
