Write a menu driven program in java

To understand that event handlers describe responses to events, not their causes To be able to write event handlers for simple event-driven systems Control Loops and Handler Methods In chapter 11, we looked at mechanisms for explicit dispatch. In that chapter, the job of the central control loop was to decide what needs to be done and then to call a helper procedure to do it. In this way, a single control loop can handle a variety of different inputs or circumstances.

Write a menu driven program in java

Step By Step Step 1: Write the Java Code The following Java code segment defines a class named HelloWorld that has one method and a static code segment. The implementation for displayHelloWorld is provided in a separate C language source file.

The method definition for displayHelloWorld also indicates that the method is a public instance method, accepts no arguments and returns no value. For more information about arguments to and return values from native methods see Arguments and Return Values.

Like other methods, native methods must be defined within a Java class.

Step 1: Write the Java Code The following Java code segment defines a class named HelloWorld that has one method and a static code segment. class HelloWorld { public native void displayHelloWorld(); static { caninariojana.combrary("hello"); } }. Jul 24,  · The program can be extended. You can use the program to create your own menu driven system. Go ahead.. Explanation. Import the Scanner. Declare the class as public; Add the void main function; Add caninariojana.comn() function with the message to enter choice. Declare input as Scanner. Take the inputs and save it in . MunavvarHushen  Hello friends, i am a CSE student and i am going to upload all the programs of various language which might be in your collage practical .

Load the Library The C code that implements displayHelloWorld must be compiled into a dynamically loadable library you will do this in Step 6: Create a Dynamically Loadable Library and loaded into the Java class that requires it.

Loading the library into the Java class maps the implementation of the native method to its definition. The following static code block from the HelloWorld class loads the appropriate library, named hello. The runtime system executes a class's static code block when it loads the class.

Create the Main Program In a separate source file, named Main. A matched set of parentheses, andfollow the method name and enclose any arguments to pass into the method.

The displayHelloWorld method doesn't take any arguments.The following figure shows many menu-related components: a menu bar, menus, menu items, radio button menu items, check box menu items, and separators.
