我想在目标文件中复制源文件,知道这两个文件必须由choosefiler选择并在文本字段中将其过去以查看完整路径,以便如何在文本字段中选择文件的完整路径choosefiler并将其放在此代码中
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
public class Main {
public static void main(String[] args) {
FileInputStream fis = null;
FileOutputStream fos = null;
try {
fis = new FileInputStream(new File(""));
fos = new FileOutputStream(new File(""));
byte[] buf = new byte[8];
int n = 0;
while ((n = fis.read(buf)) >= 0) {
for (byte bit : buf) {
System.out.print("\t" + bit + "(" + (char) bit + ")");
System.out.println("");
}
buf = new byte[8];
}
System.out.println("Copie terminée !");
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (fis != null)
fis.close();
} catch (IOException e) {
e.printStackTrace();
}
try {
if (fos != null)
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
