java 创建一个File文件对象

import java.io.*;
public class Example10_1 {
   public static void main(String args[]) {
      File f = new File("C:\\ch10","Example10_1.java");
      System.out.println(f.getName()+"是可读的吗:"+f.canRead());
      System.out.println(f.getName()+"的长度:"+f.length());
      System.out.println(f.getName()+"的绝对路径:"+f.getAbsolutePath());
      File file = new File("new.txt");
      System.out.println("在当前目录下创建新文件"+file.getName());
      if(!file.exists()) {
         try {
              file.createNewFile();
              System.out.println("创建成功");
         }
         catch(IOException exp){}
      }
   }
}
