#Simple delay function in java code

Divide and conquer – Using functions helps break a program into smaller manageable chunks, hence making debugging and testing easier. This allows them to be used by more than one program.Ģ. Lastly it’s simple to relace the functions into libraries. With functions you can define it once and call it anywhere in the program to perform the task you need and you are not limited to the number of times you call the function.

Reusability of code – functions help in removing repetition of code in a program.

Parameter list – it informs the compiler about the data type it will receive and the value to be returned.

Function name – This the name of the function.

If the fuction was to return a value, replace void with the data type of the returned value. onRejected(): JavaScript will call this function if the underlying async operation failed. Void, means that the function does not have a return value. The Object class also overloads the wait() method to allow it to take a timeout specified in milliseconds (though, as we mentioned in Chapter 2, the timeout. The then() function takes 2 callback function parameters: onFulfilled(): JavaScript will call this function if the underlying async operation succeeded.

Retur type – We have functions that return a value and functions that do not return anything.

This is very useful when working with Asynchronous tasks. The purpose of the callback function is to inform a class Sync/Async if some work in another class is done. measuretime will return the time taken by the function myFunction to execute. A CallBack Function is a function that is passed into another function as an argument and is expected to execute after some kind of event. Below is an example for finding execution time of a function using time.sleep () function. Return Value: It returns the selected element with the specified speed. It is optional and specifies the name of the queue. In this case static means the function is a not an object of the main class but a method that belongs to the main class. This could be done by defining a simple function time.sleep (n), where n will give the number of seconds in which the program has been executed. (selector).delay(para1, para2) Parameter: It accepts two parameters which are specified below- para1: It specifies the speed of the delay.

Modifier – ‘static’ is optional in a fuction defination.

Private can oly be called inside the class The only possible advantage is that you can set this to a different rate to the draw loop but since everything you display is going to be governed by draw you might as well do your time-sensitive events there. We have other access specifiers such as private and protected.Protected, the method can only be called within the class and its subslcasses. All youll achieve with setTimeout/setInterval is creating another separate loop. ‘Public’ means that the function can be called from aywhere in the program.

Access specifier – this shows the scope of availability of a fuction.

ThreadSleep.java package static void myFuction(String name, int age ) Here is a simple program where Thread.sleep() is used to pause the main thread execution for 2 seconds. The allowed nano second value is between 99. There is another overloaded method sleep(long millis, int nanos) that can be used to pause the execution of current thread for specified milliseconds and nanoseconds. To use delay function in your program you should include the 'dos.h' header file which is not a part of standard C library.

Declaration: void delay (unsigned int) Here unsigned int is the number of milliseconds (remember 1 second 1000 milliseconds). The argument value for milliseconds can’t be negative, else it throws IllegalArgumentException. Delay in C: delay function is used to suspend execution of a program for a particular time. Thread.sleep() method can be used to pause the execution of current thread for specified time in milliseconds.
