Explanation of Solution

Given code:

The given code is highlighted below.

//Main Class

class Main

{

    //Main method

    public static void main(String[] args)

    {

//A variable is declared and a value is assigned

        int waitTime = 46;

        //Try block

        try

        {

            //Print the message

            System.out.println("Try block entered");

            //Check if value is greater than 30

            if(waitTime > 30)

                //Throw an exception

throw new Exception("Time Limit Exceeded.");

            //Print the message

System.out.println("Leaving try block.");

        }

        //Catch block

        catch (Exception e)

What output is produced by the following code?int waitTime = 46;try{cout << "Try block entered.\n";if (waitTime > 30)throw waitTime;cout << "Leaving try block.\n";}catch(int thrownValue){cout << "Exception thrown with\n"<< "waitTime equal to " << thrownValue << endl;}cout << "After catch block" << endl;
Only new java code can be added after the code given:   The while loop makes multiple attempts to read a nonnegative integer from input into userAge. Use multiple exception handlers to: Catch an InputMismatchException, output "Unexpected input: The UserAge program quits", and assign retry with false. Catch an Exception and output the message of the Exception. End each output with a newline. Ex: If the input is 44, then the output is: Valid input: User's age is 44 Ex: If the input is L, then the output is: Unexpected input: The UserAge program quits Ex: If the input is -65 44, then the output is: User's age must be nonnegative Valid input: User's age is 44       import java.util.Scanner;import java.util.InputMismatchException; public class UserAge {   public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);      int userAge;      boolean retry = true;       while (retry) {         try {            userAge = scnr.nextInt();              if (userAge < 0) {…
