RandomAccessFile類close()方法
- close() 方法可在
java.io
包。 - close() 方法用於關閉此 RandomAccessFile 流並釋放與此流鏈接的所有其他係統資源。
- close() 方法是一個非靜態方法,它隻能通過類對象訪問,如果我們嘗試使用類名訪問方法,那麽我們將得到一個錯誤。
- close() 方法可能會在關閉流時拋出異常。
IOException: 執行輸入/輸出操作時可能會拋出此異常。
用法:
public void close();
參數:
- 它不接受任何參數。
返回值:
這個方法的返回類型是void
,它什麽都不返回。
例:
// Java program to demonstrate the example
// of void close() method of RandomAccessFile
import java.io.*;
class RAFClose {
public static void main(String[] args) throws Exception {
String str = "Welcome, in Java World!!!";
// Instantiate a random access file
// object with file name and permissions
RandomAccessFile ra_f = new RandomAccessFile("e:/includehelp.txt", "rw");
// By using writeUTF() method is to
// write a string value to the file by using
// UTF encoding scheme
ra_f.writeUTF(str);
// 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 EOF
ra_f.seek(0);
System.out.println("ra_f.readUTF():" + ra_f.readUTF());
// By using close() method isto
// close this stream ran_f
ra_f.close();
}
}
輸出
ra_f.readUTF():Welcome, in Java World!!!
