The System maintains the ID, Name, Residential address and the Phone number (must start with Area code) for N subscribers in one dimensional arrays. Write a menu-driven application for performing the following operations. a) Accept the Subscriber’s details b) Search for records based on one of the following and display the details. (i) Name (ii) Phone Number Note: User can enter either a part of a name or in full for searching. c) Sorts the records in the ascending order of one of the following fields based on user’s choice (i) Name (ii) Phone number d) Displays the subscribers’ details in a tabular form as shown below: Address List ID Name Address Phone Number 11 RAHUL BOSE 15TH CROSS ST. 06-234 5678 12 TARUN SHARMA 14TH AVENUE 06-456 7831 Note: Store three user names and their passwords in two arrays. When the program executes, accept a user name and a password from the user, if they are valid then allow the user to work with the system, otherwise display error message and exit the program.

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.
