- it is a java question Write a custom exception class named StringTooLongException containing a no argument constructor and a one argument constructor.arrow_forwardT/F 6) Exception is a component of the class library of both java.lang and java.io, but IOException is exclusive to java.ioarrow_forwardX1155: Throwing an Exception The method below takes in a String parameter representing a username. It should throw an Exception if the username is less than 3 characters long. The method correctly throws the exception, but something is still missing. Fix the problem. Your Answer: Feedback 1 public String validateUser (String userName) 2|{ 3 45 6 7 8|} 9 if (userName.length() < 3) { throw new Exception("userName is too short"); } return userName; Check my answer!

- Write a program that prompts the user to enter several integer numbers and store them in a one dimensional array. The size of the array should be read from the keyboard. The program should calculate and display the average of the numbers. If the user enters a value for the array size less than one, throw and handle an appropriate exception (you have to display the message array size cannot be less than one) and prompt the user to enter another array size. This process continue until the user enters the correct array size. In addition, the program should be able to handle exception thrown when there is a division by zero problem, when the index of the array is out of bound, when there is input mismatch. SLOVE IT USING JGRASP PLEASEarrow_forwardTrue or False We can define a custom generic exception.arrow_forwards and throws an exception if the second input on a line is a string rather than an int. At FIXME in the code, add a try/catch statement to catch ios_base::failure, and output 0 for the age. Ex: If the input is: Lee 18 Lua 21 Mary Beth 19 Stu 33 -1 then the output is: Lee 19 Lua 22 Mary 0 Stu 34 419894.2696446.qx3zqy7 #include <string>#include <iostream> using namespace std; int main() { string inputName; int age; // Set exception mask for cin stream cin.exceptions(ios::failbit); cin >> inputName; while(inputName != "-1") { // FIXME: The following line will throw an ios_base::failure. // Insert a try/catch statement to catch the exception. // Clear cin's failbit to put cin in a useable state. cin >> age; cout << inputName << " " << (age + 1) << endl; cin >> inputName; } return 0;}arrow_forward
- The given program reads a list of single-word first names and ages (ending with-1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an integer. At FIXME in the code, add try and except blocks to catch the ValueError exception and output 0 for the age. Ex: If the input is: Lee 18 Lua 21 Mary Beth 19 Stu 33 -1 then the output is: Lee 19 Lua 22 Mary 0 Stu 34arrow_forwardNeeded codearrow_forwardAgain --4. Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info." Ex: If the input is: 35 the output is: Fat burning heart rate for a 35 year-old: 129.5 bpm If the input is: 17 the output is: Invalid age. Could not calculate heart rate info.?.arrow_forward
- 1. When does the + operator concatenate instead of add? What happens if you try to use + on a string with an integer? Why do you think this happens? 2. If a string has 10 characters, what is the index of the last character? 3. Explain why this code causes an exception: Animal = "Tiger" Animal[0] = "L"arrow_forward-Modify your parameter constructors to call your set methods. This will cause validation of the parameter.-Create an exception class named TractorException.-Modify your setters to throw TractorException if invalid values are passed in. You may also need to add a throws clause to your parameter constructors. This way we will not have any print methods in our Tractor object defining class-Modify your main method to try and catch exceptions. It should catch TractorExceptions and general Exceptions and display an appropriate message import java.util.*; class TestException { public static void main(String s[]) { Scanner scanner = new Scanner(System.in); boolean valid=false; // validation loop while (!valid) { try { System.out.println("Enter integer:"); int number = scanner.nextInt(); // may throw an exception System.out.println("You entered "+ number); valid=true;…arrow_forwardFill-in-the-Blank The __________ block should enclose code that directly or indirectly might cause an exception to be thrown.arrow_forward
