Built-in Java Annotations: @SuppressWarnings example

Incase if you don't want to get any warnings from compiler for the known things, then you can use @SuppressWarnings annotation. For example, you are calling deprecated method, and you know that it is deprecated, to avoid compiler warnings, user @SuppressWarnings annotation.

package com.java2novice.annotations;

public class MyDeprecatedExmp {
	
	@Deprecated
	public void showDeprecatedMessage(){
		System.out.println("This method is marked as deprecated");
	}
	
	@SuppressWarnings("deprecation")
	public static void main(String a[]){
		
		MyDeprecatedExmp mde = new MyDeprecatedExmp();
		mde.showDeprecatedMessage();
	}
}
