例子
下麵的示例演示java.io.ObjectInputStream.skipBytes()方法的用法。
package com.yiibai; import java.io.*; public class ObjectInputStreamDemo { public static void main(String[] args) { String s = "Hello World!"; try { // create a new file with an ObjectOutputStream FileOutputStream out = new FileOutputStream("test.txt"); ObjectOutputStream oout = new ObjectOutputStream(out); // write something in the file oout.writeUTF(s); oout.writeUTF("This is an example"); oout.flush(); // create an ObjectInputStream for the file we created before ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt")); // skip 4 bytes and read the rest ois.skipBytes(4); for (int i = 0; i < ois.available() - 4; i++) { System.out.print("" + (char) ois.readByte()); } } catch (Exception ex) { ex.printStackTrace(); } } }
讓我們編譯和運行上麵的程序,這將產生以下結果:
llo World!
