Java check if file size is larger than 0
提问by GFlam
Hi i'm trying to create an if statement that checks the size of a file here's what i have although it's not working.
嗨，我正在尝试创建一个 if 语句来检查文件的大小，尽管它不起作用，但这是我所拥有的。
File file = new File("/path/to/file.zip");
long fileSize = file.length();
if (!(fileSize > 0));{
Toast.makeText(MainMethod.this, "Equal to 0", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(MainMethod.this, "Greater than 0", Toast.LENGTH_LONG).show();
}

You have a semicolon at the end of your IF statement which is causing the problem here.
您的 IF 语句末尾有一个分号，这是导致问题的原因。

There is a semicolon at the end of your if statement. Also, you can simplify the code somewhat by doing the following:
if 语句的末尾有一个分号。此外，您可以通过执行以下操作来稍微简化代码：
if (file.length() > 0)
System.out.println("File Greater than 0");
else
System.out.println("File LessThanEqual to 0");
Just my opinion
只是我的观点
