java 中如何遍历全部文件,如*.txt

[yeyongji]

请dx指教.

[tanghuan]

class ProcFile {
public procFile(String FileName){
File file=new File(FileName);
if (file.isDirectory()){
File[] fs=file.listFile();
for(int i=0;i<fs.length;i++){
procFile(fs.getPath());
}
}else{
//处理
...
}
}
}

譬如我想delete *.txt 该怎样实现?

去看Thinking for java 的IO流中的File.

[leonzhao]

File folder = new File("C:/temp");
File[] files = folder.listFiles();
for (int i = 0;i < files.length;i++) {
if (files[i].getName().toLowerCase().endsWith(".txt"))
files[i].delete();
}
