Task #$1$ Algorithm

$1.$ Write a program which includes identifier declarations and a statement that is needed to enable

Java to read from the keyboard. These are not part of actually completing the task of calculating

pay, so they are not included in the pseudocode. The only important difference between the

example pseudocode and the Java code is in the calculation.

$2.$ The main objective of the program is to calculate the user$$s gross pay. It calculates the gross pay

by multiplying the number of hours worked by hourly pay rate. However, it is not always

calculated this way. What if you work $45$ hours in a week? The hours that you worked over $40$

hours are considered overtime. You will need to be paid time and a half for the overtime hours

you worked. Below is the detailed pseudocode for your Task#$1$ but without the calculation part.

You need to fill in lines that tell in English what the calculation part of Task#$1$ is doing.

Display $$How many hours did you work?$.$

Input hours.

Display $$How much are you paid per hour?$.$

Input rate.

If hours are $40$ or less, then store the value of hours times rate in the pay variable

Else store the value of $40$ times rate $($regular pay$)$ added together with $1\mathrm{.}5$ times rate times the

difference of hours and $40($overtime pay$)$ in the pay variable.

Display the value in the pay variable.

Task #$2$ Compile and Execute a Program

$1.$ Compile your program using the JDK or a Java IDE as directed by your instructor.

$2.$ You should not receive any error messages.

$3.$ When this program is executed, it will ask the user for input. You should calculate several

different cases by hand. Since there is a critical point at which the calculation changes, you

should test three different cases: the critical point, a number above the critical point, and a

number below the critical point. You want to calculate by hand so that you can check the logic of

the program. Fill in the chart below with your test cases and the result you get when calculating

by hand.

$4.$ Execute the program using your first set of data. Record your result. You will need to execute the

program three times to test all your data. Note: you do not need to compile again. Once the

program compiles correctly, it can be executed many times. You only need to compile again if

you make changes to the code.

Hours Rate Pay $($hand

calculated$)$

Pay $($program

result$)$

$4010400400\mathrm{.}0$

$3010300300\mathrm{.}0$

$4510475475\mathrm{.}0$

Second: Write a program for the following problem:

One interesting application of computers is to display graphs and bar charts. Write an application

that reads five numbers between $1$ and $30.$ For each number that$$s read, your program should

display the same number of adjacent asterisks. For example, if your program reads the number $7,$

it should display $*******.$ Display the bars of asterisks after you read all five numbers.
