friend.java

用java的net包写的一个小的点到点的聊天软件。用了2小时写的

package jsm;

import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.UnknownHostException;
import java.util.ArrayList;

class Friend {
	private InetAddress ia;

	private byte[] ip = { 127, 0, 0, 1 };

	private InetSocketAddress isa;
	// 聊天纪录
	private ArrayList memo = new ArrayList();

	String name;

	public Friend(byte[] ip) throws UnknownHostException {
		// TODO 自动生成构造函数存根
		this(ip,"anonymous");
	}

	public Friend(byte[] ip, String name) throws UnknownHostException {
		// TODO 自动生成构造函数存根
		this.ip = ip;
		this.name = name;
		ia = InetAddress.getByAddress(ip);
		//以后为了更快的通信可能使用其他的端口(只要可以实现
		isa = new InetSocketAddress(ia, Receiver.PORT);
	}

	public Friend(InetAddress ia, String name) {
		this.ia = ia;
		this.name = name;
		this.ip=ia.getAddress();
		isa = new InetSocketAddress(ia, Receiver.PORT);
	}

	public final InetAddress getIa() {
		return ia;
	}

	public final byte[] getIp() {
		return ip;
	}

	public final InetSocketAddress getIsa() {
		return isa;
	}

	public final ArrayList getMemo() {
		return memo;
	}

	public final void setIa(InetAddress ia) {
		this.ia = ia;
	}

	public final void setIp(byte[] ip) {
		// 监测ip的正确性
		this.ip = ip;
	}

	public final void setMemo(ArrayList memo) {
		this.memo = memo;
	}

}
