Example:

例：

// Java program to demonstrate the example // of short readShort() method of ObjectInputStreamimport java.io.*;public class ReadShortOfOIS {public static void main(String[] args) throws Exception {// Instantiates ObjectOutputStream , ObjectInputStream // FileInputStream and FileOutputStreamFileOutputStream file_out_stm = new FileOutputStream("D:\\includehelp.txt");ObjectOutputStream obj_out_stm = new ObjectOutputStream(file_out_stm);FileInputStream file_in_stm = new FileInputStream("D:\\includehelp.txt");ObjectInputStream obj_in_stm = new ObjectInputStream(file_in_stm);// By using writeShort() method is to write// short to the obj_out_stm streamobj_out_stm.writeShort(124);obj_out_stm.writeShort(131);obj_out_stm.writeShort(182);obj_out_stm.writeShort(154);obj_out_stm.flush();while (obj_in_stm.available() > 0) {// By using readShort() method is to read// short from the obj_in_stmshort val = (short) obj_in_stm.readShort();System.out.println("obj_in_stm.readShort(): " + val);}// By using close() method is to // close all the streams file_in_stm.close();file_out_stm.close();obj_in_stm.close();obj_out_stm.close();} }

Output

輸出量

obj_in_stm.readShort(): 124 obj_in_stm.readShort(): 131 obj_in_stm.readShort(): 182 obj_in_stm.readShort(): 154
