File not found Exception when zipping a file

Question

Hello I seem to have run into a problem when trying to zip a directory.
I get the error:
java.io.FileNotFoundException: C:\Users\dojo\Documents\Programming\compress (Access is denied)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
at java.io.FileOutputStream.<init>(FileOutputStream.java:70)
at ZipUtility.zip(ZipUtility.java:31)
at ZipUtility.main(ZipUtility.java:21)
when i run the code
import java.io.File;
import java.io.FileOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
import java.io.*;
public class ZipUtility {
     public ZipOutputStream cpZipOutputStream = null;
     public String strSource = "";          
     public String strTarget = "";          
     public static long  size          = 0;     
     public static int   numOfFiles    = 0;          
     public static void main(String args[]) {
          ZipUtility udZipUtility = new ZipUtility();                    
          udZipUtility.strSource = "C:\\Users\\dojo\\Documents\\Programming\\compress\\restoreDump"; //args[0];          
          udZipUtility.strTarget = "C:\\Users\\dojo\\Documents\\Programming\\compress"; //args[1];          
          udZipUtility.zip();          
     public void zip(){                    
          try          {                              
               File cpFile = new File (strSource);                                             
               if (!cpFile.isFile() && !cpFile.isDirectory() ) {                                   
                    System.out.println("\nSource file/directory Not Found!");                                   
                    return;                         
               FileOutputStream fos = new FileOutputStream(strTarget);               
               cpZipOutputStream = new ZipOutputStream(fos);                         
               cpZipOutputStream.setLevel(9);                         
               zipFiles( cpFile);                         
               cpZipOutputStream.finish();                         
               cpZipOutputStream.close();                         
               System.out.println("\n Finished creating zip file " + strTarget + " from source " + strSource);                         
               System.out.println("\n Total of  " + numOfFiles +" files are Zipped " );               
               System.out.println("\n Total of  " + size  + " bytes are Zipped  ");          
          }     catch (Exception e){                                   
               e.printStackTrace();                    
     public void  zipFiles(File cpFile) {                    
          int byteCount;
          final int DATA_BLOCK_SIZE = 2048;     
          FileInputStream cpFileInputStream;
          if (cpFile.isDirectory()) {                              
               if(cpFile.getName().equalsIgnoreCase(".metadata")){ //if directory name is .metadata, skip it.                         
                    return;               
               File [] fList = cpFile.listFiles() ;                              
               for (int i=0; i< fList.length; i++){                                        
                    zipFiles(fList) ;                              
          else {                              
               try {          
                    if(cpFile.getAbsolutePath().equalsIgnoreCase(strTarget)){
                         return;
                    System.out.println("Zipping "+cpFile);                    
                    size += cpFile.length();                    
                    //String strAbsPath = cpFile.getAbsolutePath();                                        
                    numOfFiles++;                    
                    String strAbsPath = cpFile.getPath();                    
                    String strZipEntryName = strAbsPath.substring(strSource.length()+1, strAbsPath.length());                                        
                    //byte[] b = new byte[ (int)(cpFile.length()) ];
                    cpFileInputStream = new FileInputStream (cpFile) ;                                                                           
                    ZipEntry cpZipEntry = new ZipEntry(strZipEntryName);
                    cpZipOutputStream.putNextEntry(cpZipEntry );
                    byte[] b = new byte[DATA_BLOCK_SIZE];
                    while ( (byteCount = cpFileInputStream.read(b, 0, DATA_BLOCK_SIZE)) != -1)
                         cpZipOutputStream.write(b, 0, byteCount);
                    //cpZipOutputStream.write(b, 0, (int)cpFile.length());
                    cpZipOutputStream.closeEntry() ;
               } catch (Exception e) {                                        
                    e.printStackTrace();                              
I really have no idea why its saying access denied if anyone can help that would be great.

Read the stack trace from the bottom up. It's telling you that the error, or exception arose
at ZipUtility.zip(ZipUtility.java:21)
which is udZipUtility.zip();This line called the zip() method which threw an exception
at ZipUtility.main(ZipUtility.java:31)
which is FileOutputStream fos = new FileOutputStream(strTarget);What is the value of strTarget?"C:\\Users\\dojo\\Documents\\Programming\\compress"This is a folder, isn't it?
Read the javadoc for public FileOutputStream(String name)
       throws FileNotFoundException
If the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason then a FileNotFoundException is thrown.
