Chapter 9.1, Problem 7STQ

Explanation of Solution

“throw” statement:

  • • The keyword “throw” is used to throw an exception from the program. It is possible to throw either checked or unchecked exception.
  • • When an exception is thrown using “throw” keyword, the “try” block ends and the statements inside that block will not get executed. The control directly goes to the subsequent “catch” block whose parameter matches the exception object.

Example program:

//Main Class

class Main

{

    //Main method

    public static void main(String[] args)

    {

/*A variable is declared and a value is assigned*/

        int value = 9;

        //Try block

        try

        {

            //Check if value is greater than 30

            if(value < 10)

                //Throw an exception

throw new Exception("Value is lesser");

            //Print the message

READY CAREFULLY Java add comment to code, please write your test-cases on how you would test your solution assumptions and hence your code. Example of cases to be tested for are like : What if the array input which is expected does not exist - that is , input is a null. How should your code handle such a situation ? Maybe output some message like ”Null input case, so no output”? What if the length of the array is one ?....so on and so forth. Please Remember : Although, written as comments - You will address your test cases in the form of code and not prose In this assignment you are required to do a programs which takes as input two sorted arrays and returns a new array containing the elements found in both the sorted arrays. It is alright if the input arrays have duplicates, but the returned array should be duplicate free! Below is how the arrays are represented   ARRAY1[] = [1, 5, 6, 6, 9, 9, 9, 11, 11, 21] Here length of ARRAY1 is m.   ARRAY2[] = [6, 6, 9, 11, 21, 21, 21] Here…
Look at the image for the expected output. Use if class, scanner class, return class to do this program. Look image for the valid user input.
Could you please explain the Write Through method?
