句法:
public final void writeShort(int val);Parameter(s):
參數(shù):
int val – represents an integer value to write.

Return value:
返回值:
The return type of this method is void, it returns nothing.
此方法的返回類型為void ,不返回任何內(nèi)容。
Example:
例:
// Java program to demonstrate the example // of void writeShort(int val)a method of // RandomAccessFileimport java.io.*; class RAFWriteShort {public static void main(String[] args) throws Exception {short sh = 12478;// Instantiate a random access file// object with file name and permissionsRandomAccessFile ra_f = new RandomAccessFile("e:/includehelp.txt", "rw");// By using writeShort() method is to // write a short value to the filera_f.writeShort(sh);// by using seek() method is to // set the current file indicator// from where read/write could // start i.e. we set here 0 so reading// will be done from 0 till EOFra_f.seek(0);// By using readShort() method is to // read a short value from this fileSystem.out.print("ra_f.readShort(): " + ra_f.readShort());// By using close() method isto// close this stream ran_fra_f.close();} }Output
