以下示例显示java.io.RandomAccessFile.getFilePointer()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 Example
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());
// return the file pointer
System.out.println("" + raf.getFilePointer());
// change the position of the file pointer
raf.seek(5);
// return the file pointer
System.out.println("" + raf.getFilePointer());
// close the strea and release resources
raf.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
