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
