writeutf.java

j2se用在j2me中的打包代码,使用性很强,代码可以参考

package WriteUTF;

import java.io.*;


public class WriteUTF{

	public static void main(String args[])throws Exception{
		if(args.length!=3){
			System.out.println("wrong parameter");
			String destination=args[0];

		  //第一个string的长度
		  int num=Integer.parseInt(args[1]);
		  //输出文件名
		  String destination=args[2];
			BufferedReader br=new BufferedReader(new InputStreamReader(new FileInputStream(source)));
			DataOutputStream dos=new DataOutputStream(new FileOutputStream(destination,true));//表示的是接到文字的后面
