Java File类以抽象的方式表示文件和目录路径名。此类别用于创建文件和目录,文件查找,文件删除等。File对象表示磁盘上的特定文件/目录。
import java.io.File; public class FileDemo { public static void main(String[] args) { File f = null; String[] strs = {"test1.txt", "test2.txt"}; try { for(String s:strs ) { f = new File(s); boolean bool = f.canExecute(); String a = f.getAbsolutePath(); System.out.print(a); System.out.println(" is executable: "+ bool); } } catch (Exception e) { e.printStackTrace(); } } }
输出结果
/home/cg/root/2880380/test1.txt is executable: false /home/cg/root/2880380/test2.txt is executable: false
