自由手記

1. 使用用例：

import java.io.File;
import java.util.StringTokenizer;

public class CopyFiles extends FileUtil {
	
	private static void CopyFiles_Help(final String src, final String dest)
	{
		int nIndex = dest.lastIndexOf(File.separator);
		CreateFolders( dest.substring(0, nIndex) );
		CopyFile(src,dest);
		
	}
	public static void main(String[] args) {
		String[] strs=new String[]{
				"target\\config\\comps\\src\\usrUsb2PhdcInit.c",
				"target\\config\\comps\\src\\usrUsbDebug.c",
				"target\\config\\comps\\src\\usrUsbInit.c",
				"target\\config\\comps\\vxWorks\\40usb.cdf",
				"target\\h\\usb\\usbOsalDebug.h",
				"target\\h\\usb2\\usb2Phdc.h",
				"target\\src\\drv\\usb2\\healthcare\\usb2Phdc.c",
				"target\\src\\drv\\usb2\\healthcare\\Makefile"
		};
		
		for(int i=0;i<strs.length;i++){
			CopyFiles_Help("D:\\wind6921\\vxworks-6.9\\"+strs[i], "D:\\My Documents\\Google Drive\\pmd-medical\\usbhealthcare"+strs[i] );
		}
	}

}

2.  文件工具類

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.StringTokenizer;

public class FileUtil {

	public static  void CreateFolders(final String folders) {
		StringTokenizer st = new StringTokenizer(folders, File.separator);
		StringBuilder sb = new StringBuilder();
		String osname = System.getProperty("os.name");
		if (osname.compareToIgnoreCase("linux") == 0)
			sb.append(File.separator);

		while (st.hasMoreTokens()) {
			sb.append(st.nextToken());
			File file = new File(sb.toString());
			if (!file.exists())
				file.mkdir();
			sb.append(File.separator);
		}

	}

	
	public static  boolean CopyFile(final String src, final String dest) {
		File srcFile = new File(src);
		File destFile = new File(dest);
		try {
			if(!destFile.exists())
				destFile.createNewFile();
			
			FileInputStream fin = new FileInputStream(srcFile);
			FileOutputStream fout = new FileOutputStream(destFile);
			int n = 0;
			byte[] buf = new byte[4096];
			while ( (n = fin.read(buf)) != -1 ) {
				fout.write(buf, 0, n);
			}
			
			fout.close();
			fin.close();

		} catch (FileNotFoundException e) {
			e.printStackTrace();
			return false;
		} catch (IOException e) {
			e.printStackTrace();
			return false;
		}

		return true;
	}

}
