基于java的多线程断点续传程序源代码

自己为了课程设计写的程序，基于java的多线程断点续传程序

public class CLXBlock 
{
	public static final int BLOCK_SIZE =128*1024;
	
	public int size =128*1024;
	
	public int start = 0;
	public int status = 0;  //0 prepare; 1 downloading; 2 finish
	public int num;
	public byte[] buffer = new byte[BLOCK_SIZE];
}
