java io遍历目录，在造出java文件，并读出内容？

提示拒绝访问怎么办

Answer 1

public static void main(String[] args) throws IOException {
File file = new File("E:/JavaExercise/eclipse-workspace/0801/src");
File[] files = file.listFiles();
// FileInputStream fis = new FileInputStream(file + "/");
FileInputStream fis = null;
if (files != null && files.length>0) {
for (File f : files) {
if (f.isFile()) {
fis = new FileInputStream(file + "/" + f.getName());
}
}
byte[] b = new byte[files.length];
int c = 0;
for (File f : files) {
if (f.isFile() && f.getName().endsWith(".java")) {
while ((c = fis.read(b, 0, b.length)) != -1) {
System.out.println(b);
}
}
}
}
