ObjectInputStream类readShort()方法 (ObjectInputStream Class readShort() method)

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

  readShort()方法在java.io包中可用。

• readShort() method is used to read 2 bytes of short value from this ObjectInputStream.

  readShort()方法用于从此ObjectInputStream读取2个字节的短值。

• readShort() 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.

  readShort()方法是一种非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

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

  readShort()方法在读取简短内容时可能会引发异常。

  IOException: This exception may throw when getting any input/output error while performing.

  IOException ：在执行过程中遇到任何输入/输出错误时，可能引发此异常。

Syntax:

句法：

    public short readShort();

Parameter(s):

参数：

• It does not accept any parameter.

  它不接受任何参数。

Return value:

返回值：

The return type of the method is short, it returns the 2 bytes (i.e. 16 bit) short read.

该方法的返回类型为short ，它返回2个字节(即16位)的短读​​。

Example:

例：

// Java program to demonstrate the example
// of short readShort() method of ObjectInputStream
import java.io.*;
public class ReadShortOfOIS {public static void main(String[] args) throws Exception {// Instantiates ObjectOutputStream , ObjectInputStream
// FileInputStream and FileOutputStream
FileOutputStream 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 stream
obj_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_stm
short 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

输出量

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