ObjectInputStream類readUnsignedShort()方法 (ObjectInputStream Class readUnsignedShort() method)

• readUnsignedShort() method is available in java.io package.

  readUnsignedShort()方法在java.io包中可用。

• readUnsignedShort() method is used to read 2 bytes (i.e. 16 bit) unsigned short of data from the ObjectInputStream.

  readUnsignedShort()方法用于從ObjectInputStream讀取2個(gè)字節(jié)(即16位)的無符號缺少數(shù)據(jù)。

• readUnsignedShort() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  readUnsignedShort()方法是一個(gè)非靜態(tài)方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

• readUnsignedShort() method may throw an exception at the time of reading unsigned short.

  readUnsignedShort()方法在讀取unsigned short時(shí)可能會引發(fā)異常。

  • IOException: This exception may throw when getting any input/output error while performing.IOException ：在執(zhí)行過程中遇到任何輸入/輸出錯誤時(shí)，可能引發(fā)此異常。
  • EOFException: This exception may throw when this stream is reached its end.EOFException ：當(dāng)此流到達(dá)末尾時(shí)，可能引發(fā)此異常。

Syntax:

句法：

public int readUnsignedShort();

Parameter(s):

參數(shù)：

• It does not accept any parameter.

  它不接受任何參數(shù)。

Return value:

返回值：

The return type of the method is int, it returns the unsigned short read.

方法的返回類型為int ，它返回?zé)o符號的短讀取。

Example:

例：

// Java program to demonstrate the example // of int readUnsignedShort() method of // ObjectInputStreamimport java.io.*;public class ReadUnsingedShortOfOIS {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 readUnsingedShort() method is to read// unsigned short from the obj_in_stm and returned// as an integerint val = (int) obj_in_stm.readUnsignedShort();System.out.println("obj_in_stm.readUnsignedShort(): " + 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.readUnsignedShort(): 65412 obj_in_stm.readUnsignedShort(): 131 obj_in_stm.readUnsignedShort(): 65354 obj_in_stm.readUnsignedShort(): 154
