无法使用for创建.txt

Question

我想在Eclipse中使用for创建10个txt文件 为什么当我这样做时我得到错误？

for (int i=0; i< 10; i++) 
File i = new File("C:\\Users\\User\\Desktop\\FOLDER- OS test\\primer" + i + ".txt");

    - i cannot be resolved to a variable
    - i cannot be resolved to a variable

您正尝试重新分配已定义为i的变量int。只需为文件使用另一个变量名称，如下所示：

for (int i=0; i< 10; i++) {
   File foo = new File("C:\\Users\\User\\Desktop\\FOLDER- OS test\\primer" + i + ".txt");
   foo.createNewFile();
}
