smp126.java

本程序将文本区中的文字写入一个文件中。很好用的

import java.io.*;

public class smp126 
{
	public static void main(String args[])
	{
		try
		{
			File fl1=new File("smp125.txt");
			File fl2=new File("smp126.txt");
			RandomAccessFile raf1=new RandomAccessFile(fl1,"r");
			RandomAccessFile raf2=new RandomAccessFile(fl2,"rw");
			long len1=raf1.length(),len2=raf2.length();
			long flpt=0;
			raf2.seek(len2);
			raf2.writeBytes(""+'\n');
			while(flpt<len1)
			{
				String str=raf1.readLine();
				raf2.writeBytes(str+'\n');
				flpt=raf1.getFilePointer();
			}
			raf1.close();
			raf2.close();
		}
		catch(Exception e)
		{
			System.out.println("Exception");
		}
	}
