Question

In JAVA   

•use JOptionPane (not Scanner)

•Write a method called calcWage which takes two parameters:

•Hours worked

•Hourly Rate

calcWage will return the amount needed to be paid, by multiplying the hours worked by the hourly rate.

•Write a main method that asks the user for the number of hours they worked on 3 different days and their daily rate. Call calcWage to calculate the total wage. Use String.format to format the output. Use a LOOP!

•Add documentation comments to your methods and generate the Javadoc. Attach a screenshot of the Javadoc for your method.

Explanation / Answer

// INPUT USING A SCANNER

Firstly create a new eclipse project named SCANNER_INPUT_1

Add a main class (with main method)

Type (or copy/paste) code and then run the following program:

import java.util.scanner;

/*complete the program that prompts the user to enter two integers, then outputs the integer which is smaller and which is larger.  

*/

public class main{

public static void main(String[] args) {

Scanner kbd= new Scanner(System.in);

// TODO: declare input 1 and input 2 as integers, each initailized to 0

// then declare mininput and maxinput as integer and initialized to 0 each

// prompt the user for the user for the first input value

//get the value of input input1 as user input, using the kdb Scanner

// then prompt the second value as input

// get the value of input2 as user input using the kdb Scanner

// set the mininput to the smaller of input1 and input2

minInput= Math.min(input1,input2);

// set the maxinput to the larger of input1 and input2

maxIput=Math.max(input1,input2);

//output the smaller integer

//output the larger integer

} // end main method

} // end main class

THEN TEST THE PROGRAM USING THE INPUTS:

1. 12 and 23, and

2. 23 and 12.

//INPUT USING AN INPUT DIALOG

now, write a program that implements input using more graphical dialog boxes.

create a new Eclipse project named SCANNER_INPUT_2

add a main class (with a main method)

Type (or copy/paste) code and then run the following program:

import javax.swing.JOptionPane;

public class Main{

public static void main(String[] args) {

String Input;

// TODO: declare input 1 and input 2 as integers, each initailized to 0

// then declare mininput and maxinput as integer and initialized to 0 each

// Get the value of input1 as user input using an input dialog

Input = JOptionPane.showInputDialog("Enter the first integer");

input2 = Integer.parseInt(Input);

// get the value of input2 as user input using an input dialog(using previous step as a guide)

//set mininput to the smaller of input1 and input2

minInput=Math.min(input1,input2);

//set maxinput to the larger of input1 and input2

maxInput=Math.max(input1,input2);

// using a message dialog ,output the smaller integer

JOptionPane.showMessageDialog("smaller number"+minInput);

// using a message dialog ,output the larger integer

JOptionPane.showMessageDialog("larger number"+maxInput);

} // end main method

} // end main class

now test the program using the inputs:

1. 12 and 23, and

2. 23 and 12

// CalcWage.java

// Employee.java
