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

Its the example of native method............
import java.util.*;
class ReadFile {
//Native method declaration
native byte[] loadFile(String name);
//Load the library
static {
System.loadLibrary("nativelib");
}
public static void main(String args[]) {
byte buf[];
//Create class instance
ReadFile mappedFile=new ReadFile();
//Call native method to load ReadFile.java
buf=mappedFile.loadFile("ReadFile.java");
//Print contents of ReadFile.java
for(int i=0;i<buf.length;i++) {
System.out.print((char)buf[i]);
}
}
}
import java.util.*;
class ReadFile {
//Native method declaration
native byte[] loadFile(String name);
//Load the library
static {
System.loadLibrary("nativelib");
}
public static void main(String args[]) {
byte buf[];
//Create class instance
ReadFile mappedFile=new ReadFile();
//Call native method to load ReadFile.java
buf=mappedFile.loadFile("ReadFile.java");
//Print contents of ReadFile.java
for(int i=0;i<buf.length;i++) {
System.out.print((char)buf[i]);
}
}
