本文介绍了两个用于文件和目录移动及数据复制的方法，详细解释了如何使用Java实现文件的移动和复制功能。

public class FileAccess
{

public static boolean Move(File srcFile, String destPath)
{
// Destination directory
File dir = new File(destPath);

// Move file to new directory
boolean success = srcFile.renameTo(new File(dir, srcFile.getName()));

return success;
}

public static boolean Move(String srcFile, String destPath)
{
// File (or directory) to be moved
File file = new File(srcFile);

// Destination directory
File dir = new File(destPath);

// Move file to new directory
boolean success = file.renameTo(new File(dir, file.getName()));

return success;
}

public static void Copy(String oldPath, String newPath)
{
try {
int bytesum = 0;
int byteread = 0;
File oldfile = new File(oldPath);
if (oldfile.exists()) {
InputStream inStream = new FileInputStream(oldPath);
FileOutputStream fs = new FileOutputStream(newPath);
byte[] buffer = new byte[1444];
int length;
while ( (byteread = inStream.read(buffer)) != -1) {
bytesum += byteread;
System.out.println(bytesum);
fs.write(buffer, 0, byteread);
}
inStream.close();
}
}
catch (Exception e) {
System.out.println( "error ");
e.printStackTrace();
}
}
public static void Copy(File oldfile, String newPath)
{
try {
int bytesum = 0;
int byteread = 0;
//File oldfile = new File(oldPath);
if (oldfile.exists()) {
InputStream inStream = new FileInputStream(oldfile);
FileOutputStream fs = new FileOutputStream(newPath);
byte[] buffer = new byte[1444];
while ( (byteread = inStream.read(buffer)) != -1) {
bytesum += byteread;
System.out.println(bytesum);
fs.write(buffer, 0, byteread);
}
inStream.close();
}
}
catch (Exception e) {
System.out.println( "error ");
e.printStackTrace();
}
}
}
