- Suppose that statement2 causes an exception in the following try-exceptblock:try:statement1statement3except Exception1:# Handle exception 1except Exception2:# Handle exception 2statement4Answer the following questions:■ Will statement3 be executed?■ If the exception is not caught, will statement4 be executed?■ If the exception is caught in the except block, will statement4 be executed?Exception Project JAVA Create a Java program that searches for a student’s ID or name in a text file, complete the findID() and findName() functions. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains a name and ID separated by a space. Function findID() has two parameters: a student's name (string) and the text file's contents (infile, input file variable). The function findID() returns the ID associated with the student's name if the name is in the file, otherwise the function throws a runtime error with the message "Student ID not found for studentName", where studentName is the name of the student. Function findName() has two parameters: a student's ID (string) and the text file's contents (infile). The function findName() returns the name associated with the student's ID if the ID is in the file, otherwise the function throws a runtime error with the message…Task 2: Fault Intolerant When reviewing logfiles, we need to be aware of the first time an ERROR crops up in the log. This can help us see how and when things might have gone wrong. For this task we will find the first event/message of type ERROR and print it out. Instructions 1. Create a file called Fault Intolerant.java 2. As with Task 1, open the file for reading in a try-catch block. 3. Read through the file line by line 4. If the message/event type is ERROR, throw a new Exception with the line as the exception message. 5. Catch the thrown exception and print out the message to the user then exit the program immediately. 6. If no error message is found, exit the program without printing anything. Sample Input/Output Example 1: 1: 1631077133.1621487 ERROR Carrier signal lost. Example 2: Cannot find logfile! Exiting...
- Design and implement a program that creates an exception classcalled StringTooLongException, designed to be thrown when astring is discovered that has too many characters in it. In the maindriver of the program, read strings from the user until the userenters "DONE". If a string that has too many characters (say 20) isentered, throw the exception. Allow the thrown exception toterminate the programWhen an exception occurs it is said to have been thrown. handled. O caught. O resolved.What is a throw point? 2. What is an exception handler? 3. Explain the difference between a try block and a catch block. 4. What happens if an exception is thrown, but not caught? 5. Complete the following function that searches a numeric array for a specified value. The function should return the subscript of the element containing the value if it is found in the array. If the value is not found, the function should throw an exception. int searchArray(int array[], int size, int value){ int index = 0; // Used as an index to search array int subscript = -1; // To record position of search value while (index < size && subscript == -1) { if (array[index] == value) // If the value is found ___________________________________________________ ___________________________________________________ } if (subscript == -1) ___________________________________________________ return subscript; } Bonus…
- Errors produced when calling 3. Find the maximum element from the BST or4. Find the minimum element from the BST before adding elements so the program should output 0(0) instead of an error "Exception in thread "main" java.lang.NullPointerException: Cannot read field "right" because "<local1>" is null at BST.findMax(BST.java:109) at BST.main(BST.java:194)" "Exception in thread "main" java.lang.NullPointerException: Cannot read field "left" because "<local1>" is null at BST.findMin(BST.java:118) at BST.main(BST.java:197)"Steps to be followed: Create a class called MyThread that extends the Thread class. Declare an instance variable int limitToStop in the MyThread class. Create a parameterized constructor in the MyThread class that takes an int as a parameter to initialize a limitToStop instance variable. Override the run() method in the MyThread class. In the run() method, put a for-loop that goes from 0 to limitToStop. The block associated with the for-loop should print out only the odd numbers. Call Thread.sleep(1000) after every number you print out in the for-loop you created in the previous step. The Thread.sleep(1000) method throws an InterruptedException , which is a checked exception. Therefore, we need to enclose the Thread.sleep(1000) call in a try block. Also, add a catch block associated with the try that catches the InterruptedException and prints out the exception information using the printStackTrace() method. Create a MyThread variable using the new keyword in the main()…JAVA CODE Unchecked exceptions are exceptions that are usually the result of a mistake and we aren't expected to handle, while checked exceptions are exceptions that we reasonably expect to occur that we should handle whenever possible. Name one type of unchecked exception and one type of checked exception, and give an example of situations that might cause those exceptions to be thrown.
- Please written by computer source Java exceptions.Create a custom error with a number field. Create a loop from 0 to 1500. Divide each number from 0 to 1500 by 17 and if it is divisible without a remainder, then throw a custom exception with a number that is divided entirely. Catch all the exceptions and display a list of all the numbers from 0 to 1500, which are completely divided by 17. Provide full source code and step-by-step explanation.Write the source code of the exception FlightException.First, create the custom exception class called OutOfStockException by creating a new class that extends the Exception class The class has a single constructor that takes a single argument, a string called message. The message argument is passed to the parent class (Exception) via the super keyword. Create the Store class and import the java.util.HashMap and java.util.Map classes The Store class is defined with a private Map called products, which is used to store the product names and their corresponding quantities. Create a default constructor that initializes the products map with three items: "apple", "banana", and "orange", with respective quantities of 10, 5, and 0. Define thepurchase method , which takes two arguments: a product name and a quantity to be purchased. This method throws an OutOfStockException if either the specified product is not available in the store or if the requested quantity is greater than the quantity available in stock. The method first…
