Start BlueJ and create the project lab$02$ under your cm$111$lab folder. Complete the programming exercises that follow.

To automatically clear the terminal when you execute you program, in the project window, click the View menu and select Show terminal $($or go to terminal window if open$).$ Click on the Options menu in the terminal window and click on "Clear screen at method call".

Programming Exercises.

$1.$ Create a class called Test. Then type the following code into the class. Note: don$$t forget to delete the extra lines of code that were generated by BlueJ. Compile the program and execute it$.$ Notice the different output generated by each printf statement. This occurs because the equation in the first printf is quoted and treated as a String whereas the second printf equation is not quoted and thus executed before being printed.

public class Test $\{$

public static void main$($ String$[]$ args$)$

$\{$

System.out.printf$("3\mathrm{.}5*4/22\mathrm{.}5$ is: $")$;

System.out.printf$("\%2\mathrm{.}2$f$\%$n$",3\mathrm{.}5*4/2-2\mathrm{.}5)$;

$\}$

$2.$ Create a new class called DisplayJava $($in the same lab$02$ project$).$ Declare four String variables: line$1,$ line$2,$ line$3,$ and line$4.$ Initialize each String variable with text to produce the result below. Think about using a $4$x$28$ grid to do the layout on paper first. The main method should display the following pattern in the terminal window.

$3.$ Create a new class called Rectangle $($in the same lab$02$ project$).$ The main method should output your name, lab number, and the output of the calculation for the area of a rectangle and the perimter. Create the variables width, length, area, and perimeter of Type Double. Use the numbers $2\mathrm{.}5$ for width and $4\mathrm{.}0$ for length for initial valuses.

Remember the area of a rectangle is width $*$ length and the perimeter is $2*$ width $+2*$ length.

Here is the expected output:

Name: $,$ Lab#: $2$

The area of a rectangle with length $4\mathrm{.}0$ and width $2\mathrm{.}5$ is: $10\mathrm{.}00$

The perimeter of a rectangle with length $4\mathrm{.}0$ and width $2\mathrm{.}5$ is: $13\mathrm{.}00$

Upon completion of these exercises show the instructor then upload DisplayJava.java and Rectangle.java to D$2$L$.$
