以下示例显示java.io.RandomAccessFile.close()方法的用法。
package com.jc2182;
import java.io.*;
public class RandomAccessFileDemo {
public static void main(String[] args) {
try {
// create a new RandomAccessFile with filename test
RandomAccessFile raf = new RandomAccessFile("c:/test.txt", "rw");
// write something in the file
raf.writeUTF("Hello World");
// set the file pointer at 0 position
raf.seek(0);
// read and print the contents of the file
System.out.println("" + raf.readUTF());
// close the strea and release resources
System.out.println("Closing Stream...");
raf.close();
System.out.println("Stream Closed.");
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
假设我们有一个文本文件c:/test.txt,其内容如下。该文件将用作我们示例程序的输入 -
让我们编译并运行以上程序,这将产生以下结果-
Hello World
Closing Stream...
Stream Closed.
