无法为创建.txt

Question

我想在Eclipse中用for创建10个txt文件，但是为什么我这么做的时候会出错？

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

    - Syntax error, insert ";" to complete Statement
    - i cannot be resolved to a variable
    - i cannot be resolved to a variable

您正在尝试重新分配给变量 i，该变量已定义为 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();
}
