Grade For this exercise, you are going to write a recursive function that counts down by twos to a Blastoff! Enter starting number: 10 10 8 6 4 2 Blastoff! More Your recursive function will not actually print. It will return a String that can be printed from the main function. Each recursive call will add on to that string. In your main function, prompt the user for a starting value, then print the results.

Simple try-catch Program This lab is a simple program that demonstrates how try-catch works. You will notice the output when you enter incorrect input (for example, enter a string or double instead of an integer). Type up the code, execute and submit the results ONLY. Do at least 2 valid inputs and 1 invalid. NOTE: The program does not stop executing after it encounters an error! CODE: import java.util.Scanner; public class TryCatch Example Simple { public static void main(String[] args) { Scanner input = new Scanner(System.in); int num = 0; System.out.println("Even number tester.\n"); System.out.println("Enter your name: "); String name = input.nextLine(); while (true) { try { System.out.println("Enter an integer : ");

Write all the code within the main method in the TestTruck class below. Implement the following functionality. Construct two Truck objects: one with any make and model you choose and the second object with gas tank capacity 10. If an exception occurs, print the stack trace. Print both Truck objects that were constructed. import java.lang.IllegalArgumentException ; public class TestTruck { public static void main( String[] args ) { // write your code here
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.…
TASK 3. Console Input and Output.

It's a good practice to release the resource that was acquired sc.close(); // Display the result System.out.printf( "Provided Integers: %4d and %4d, the total is %5d\n", a, b, (a + b)); } To simplify the task, we came out with the idea to use Methods. Implement a method to add two integers.
1. ArrayIndexOutOfBoundsException Given the following code: public class ExceptionTest{ public static void main( String[] args ){ String nums[] = {“one”, “two”, “three”}; for( int i=0; i<=3; i++ ){ System.out.println(nums[i]); } } } Compile and run the TestExceptions program. The output should look like this: one two three Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3 at ExceptionTest.main(1.java:4) Modify the TestExceptions program to handle the exception. The output of the program after catching the exception should look like this: one two three Exception caught: Array Index 3 is out of bounds
