- 1-Write a JAVA program that reads an array from input file and invokes twodifferent methods Sort and Max ,that sorts the elements of the array and findsthe Max element and writes out the resulted array in to output file . Usetwo interfaces for methods and throw Exception Handling for Out Of Boundindex for the arrayChallenge 1: Division.java You have to implement a Division class that divides two numbers given by the user. The program should handle exceptions that could be thrown during operation: If the second number is 0 If any of the numbers is not a valid number, such as a letter.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…
- Rules: Corner cases. Throw the specified exception for the following corner cases: Throw an IllegalArgumentException if the client calls either addFirst() or addLast() with a null argument. Throw a java.util.NoSuchElementException if the client calls either removeFirst() or removeLast when the deque is empty. Throw a java.util.NoSuchElementException if the client calls the next() method in the iterator when there are no more items to return. Unit testing. Your main() method must call directly every public constructor and method to help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. Your implementation must achieve the following worst-case performance requirements: A deque containing n items must use at most 48n + 192 bytes of memory, not including the memory for the items themselves. Each deque operation (including construction) must take constant time. Each iterator operation (including construction) must take…a) Write a method in java that searches a numeric array for a specified value. The method should return the subscript of the element containing the value if it is found in the array. If the value is not found , the method should throw an exceptionof the Exception class with the error message “Element not found”. b) Write an exception class that can be thrown when a negative number is passed to a method.(Creating Custom Exception Class) Write a Password class that stores a password string. Passwords must contain at least seven alpha-numeric characters, with at least one letter and one digit. Also write an InvalidPasswordException class that extends Exception. The Password constructor should throw an InvalidPasswordException, which should report an appropriate message based on a given string (e.g. if the string contains no digits, the exception should report this fact). Use java swing to write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Some sample screenshots are shown below:
