问题复制文件 [英] Problem copy file
问题描述
我正在将文件复制到其他目的地。我的代码无法按预期工作。任何人都帮我。我收到此错误消息--->
java.io.FileNotFoundException：C ：\Documents and Settings \XXXXXXX \ MyMy Documents（访问被拒绝）
在java.io.FileOutputStream.open（本机方法）
在java.io .FileOutputStream。< init>（FileOutputStream.j ava：179）
at java.io.FileOutputStream。< init>（FileOutputStream.j ava：131）
在test1.PilihFail $ Salin2.run（PilihFail.java:111）
代码是：
private int currentValue;
public void run（）{
BufferedInputStream in = null;
BufferedOutputStream out = null;
尝试{
文件inFile =新文件（jtfOpen.getText（）。trim（））;
in = new BufferedInputStream（new FileInputStream（inFi） le））;
文件outFile =新文件（jtfSave.getText（）。trim（））;
out = new BufferedOutputStream（new FileOutputStream（outFile） ））;
long totalBytes = in.available（）;
jpb.setValue（0）;
jpb.setMaximum（100）;
int r;
long readBytes = 0;
byte [] b = new byte [10];
while（（r = in.read（b，0，b.length））！= -1）{
out.write（b ，0，r）;
readBytes + = r;
currentValue =（int）（readBytes * 100 / totalBytes）;
jpb.setValue（currentValue）;
}
}
catch（FileNotFoundException ex）{
ex.printStackTrace（）;
}
catch（IOException ex）{
ex.printStackTrace（）;
}
最后{
尝试{
if（in！= null）in.close（）;
if（out！= null）out.close（）;
}
catch（Exception ex）{}
}
}
i am working in copying file to other destination.my code doesnt work as expected.can anybody help me.i got this error message --->

1.）发布代码时请使用代码标签。
2.）访问被拒绝是一个安全问题。您是否拥有试图访问的文件的权限？
1.) Please use code tags when posting code.
2.) Access denied is a security issue. Do you have rights to the file you are trying to access?
