java - 无法使用 for 创建 .txt

Question

我想在 Eclipse 中使用 for 创建 10 个 txt 文件，但是为什么当我这样做时会出现错误？

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

Multiple markers at this line    - Syntax error, insert "AssignmentOperator Expression" to complete      Assignment    - File cannot be resolved to a variable    - Syntax error, insert ";" to complete Statement    - i cannot be resolved to a variable    - i cannot be resolved to a variable

Answer 1

您正在尝试重新分配给变量i，该变量已被定义为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();
}
