Below is a detailed breakdown of its components:1. **Package and Imports:** - The program is contained within the `int2200.week7` package. - It imports the `java.util.Scanner` class to allow user input.2. **Main Class (`arraySearch`):** - The main class is named `arraySearch`.3. **Main Method (`main`):** - The `main` method is the entry point of the program. - An array `numbers` is initialized with a set of integer values: `{2, -9, 0, 5, 12, -25, 22, 9, 8, 12}`. - A boolean variable `foundit` is declared and initialized to `false` to track if the searched number is found.4. **User Input:** - A `Scanner` object named `input` is created to capture user input. - The program prompts ### Java Program Exercise: Implementing a Do-While Loop**Task:**Modify the following Java program to achieve the specified output using a do-while loop.**Requirements:**- **Provide:** - Detailed documentation and the exact output as described.**Hint:** A do-while loop is required for this task.**Expected Program Output:**```==>> Array Search programEnter a number to search for: 2found it! :)Enter any number to continue or number 0 to exit: 5==>> Array Search programEnter a number to search for: 6Sorry not found it! :(Enter any number to continue or number 0 to exit: 0==>> End of the Search Program!```This task will help you understand the use of the do-while loop in a Java program. Make sure to provide the complete program with necessary comments explaining the logic for full understanding.

8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…
