Built-in Java Annotations: @Deprecated example


Description:

The @Deprecated annotation will be used to inform the compiler to generate a warning whenever a program uses a method, class, or field with the @Deprecated annotation. It is good to document the reason with Javadoc @deprecated tag. Make a note of case difference with @Deprecated and @deprecated. @deprecated is for documentation purpose.


Code:
package com.java2novice.annotations;

public class MyDeprecatedExmp {
	
	/**
     * @deprecated
     * reason for why it was deprecated
     */
	@Deprecated
	public void showDeprecatedMessage(){
		System.out.println("This method is marked as deprecated");
	}
	
	public static void main(String a[]){
		
		MyDeprecatedExmp mde = new MyDeprecatedExmp();
		mde.showDeprecatedMessage();
	}
}

Procedural Vs Object-oriented Programs
In procedural program, programming logic follows certain procedures and the instructions are executed one after another. In OOP program, unit of program is object, which is nothing but combination of data and code.

In procedural program, data is exposed to the whole program whereas in OOPs program, it is accessible with in the object and which in turn assures the security of the code.
Famous Quotations
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
