Which is a reserved word in the Java programming language?
Answer: Option

The word "native" is a valid keyword, used to modify a method declaration.

Option A, D and E are not keywords. Option C is wrong because the keyword for subclassing in Java is extends, not 'subclasses'.

'native' is a reserved keyword in Java. It is used to modify the methods and implementation of code can be done in other languages (c, c++).

Where to use this 'native' keyword?

When You need to call a library from Java that is written in other languages. Because while developing any application (or) something.

In such cases Java may not support your needs, then we can write code in other language and add it to the Java library.

Now we can access that library by using 'native' keyword. (ie. JNI) Java native interface.

I hope that this will make you understand a till bit better.

Its the example of native method............

import java.util.*;

class ReadFile {
//Native method declaration
native byte[] loadFile(String name);
//Load the library
static {

public static void main(String args[]) {
byte buf[];
//Create class instance
ReadFile mappedFile=new ReadFile();
//Call native method to load
//Print contents of
for(int i=0;i<buf.length;i++) {
