Payroll Evaluation 1

Java Simple Console Application: Payroll Evaluation - 1 Week

Introduction

The primary type of application you can create with the Java language is a console or teminal applicaiton. In this exercise, we will have an introduction to Java by creating a simple small console application.

As Java is a free language, you can download and install it on your computer. There are various ways you can create a Java application, including the Command prompt or a terminal. You can also use a programming environment such as Eclipse (which is free). For our example, we will use Visual Studio Code (which also is free).

Practical Learning: Creating the Application

Start Visual Studio Code
On the main menu, click File and click New File...
In the New File text box, type Exercise.java and press Enter
In the Create File dialog box, ccreate a folder named PayrollEvaluation1 and display it in the top combo box
Set the file name to Exercise.java and press Enter

In the empty document, type the following:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);

        System.out.print("Payroll Evaluation\n");
        System.out.print("----------------------------------------------\n");

Using an Opposite Conditional Statement

In the previous section, we use a Greater Than operator to check a condition. That operator has an opposite, which is the Less Than Or Equal operator. We will uase apply as an example.
