Step 2:   A BlueJ: Create New Package window appears. Enter any package name (Eleven in this example) and click on OK
                        button.
                 Step 3:   The package with the name Eleven will appear on the BlueJ window.













                 Step 4:   Double-click on the given package (Eleven in this case). In the new package window, click on the New Class tab
                        on the left pane.
                 Step 5:   The Create New Class dialog box appears. In the text box, enter the class name (say Area) and click on OK button.
























                 Step 6:   Double-click to open the class Area. Type the program. Compile and debug it until ‘Class compiled - no syntax
                        errors’ message is obtained.
                 Step 7:  Close both the class and the package.






















                         Note: We can create multiple classes under any package by the above-mentioned steps.
