Write a Java program to create your own Exception class named DuplicateException. This exception class throws an error if an array chatains duplicate elements. Write a program in Java that reads $5$ elements from console to initialize the array and pass the array in a method named findSum $().$ If the array contains any duplicate elements, the findSum $()$ method throws the DuplicateException. Otherwise, the method calculates the sum of five elements and prints the result. See the sample input$/$output section for the desired inputs and outputs.
