如何在 Java 中创建目录?
How can I make a directory in Java?
我正在尝试创建一个新的文件目录,但是函数 mkdir()
不起作用,mkdirs()
。
这是我的代码:
...
while (leitor.hasNext()){
String [] plv = LerPalavras(tamMem, leitor);
Arrays.sort(plv);
String nomeTemp = "/temp/temp" + contador + ".txt"; // I need to create this directory
try{
escritor = new FileWriter(nomeTemp);
for (int i = 0; i < tamMem; i++) {
escritor.write(plv[i] + " ");
}
escritor.close();
} catch (IOException e){
System.out.println(e.getMessage());
}
contador++;
}
...
编辑:我进行了编辑,现在可以使用了!
File pastaTemp = new File("/temp/temp");
pastaTemp.mkdirs();
while (leitor.hasNext()){
String [] plv = LerPalavras(tamMem, leitor);
Arrays.sort(plv);
File arqTemp = new File (pastaTemp, contador + ".txt");
try{
escritor = new FileWriter(arqTemp);
for (int i = 0; i < tamMem; i++) {
escritor.write(plv[i] + " ");
}
escritor.close();
} catch (IOException e){
System.out.println(e.getMessage());
}
contador++;
}
尝试分两步进行。首先,调用 File.mkdirs()
创建整个目录结构,如有必要,然后创建传递给 FileWriter
的文件:
try {
File folder = new File("/temp/temp");
folder.mkdirs();
// then create a file object at this location
File file = new File(folder, contador + ".txt");
escritor = new FileWriter(file);
// the rest of your code
}
catch (Exception e) {
}
