Java Basic(78)-File Class

import java.io.File;

class apples{

public static void main(String[] args){

File x = new File("C:\\java\\abc.txt"); →必須是\\

if(x.exists())

System.out.println(x.getName() + " exist!");

else

System.out.println("this things doesn't exists!");

}

}

檢查它存在與否：

this things doesn't exists!
