Hey, could you please give an example of using "native" keyword?.

I want simple program for 'native' keyword?

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]);
}
}
}

When we can modify the method declaration using "native" keyword in java ?

Can you please give clear explanation about of native keyword ?

May you tell me where do we use native keyword?

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