Package probelem in java?

Question

Please help me. I have two packages named app and Util. Util is inside app. In Util i have the file BitUtils.java and in app i have CertkillerApp.java which is the driver file. I am getting error. Please help me.
BitUtils.java :

package Util;
public class BitUtils {

public static void process(new byte[]) {

System.out.println("Inside method byte");
}
}

CertkillerApp.java
package app;
public class CertkillerApp {
public static void main(String[] args) {
byte[] bytes = new byte[256];
Util.BitUtils.process(bytes);
}
}

Output :

D:\APP>javac CertkillerApp.java
.\Util\BitUtils.java:4: illegal start of type
public static void process(new byte[]) {
^
.\Util\BitUtils.java:8: expected
}
^
.\Util\BitUtils.java:4: missing method body, or declare abstract
public static void process(new byte[]) {

{
public static void process(byte[]nn)
{

System.out.println("Inside method byte");

Util.BitUtils.process(bytes);
}

Answer 2

I think u need to declare package as

package app.util;


and when u r using the process method u need to import the package like this


import app.util.*;

and use the method as BitUtils.process();

i think this wil work fine.

Answer 3

either add
import app.util.bitutils
or
change
Util.BitUtils.process(bytes) ---> this as
app.util.bitutils.process
