使用socket实现网络聊天室和私聊功能

public class SocketEvent {  private int type =0;  private String msg ="";  private String keyIP =""; // 关键IP  private String temporaryIP =""; // 临时IP  public SocketEvent() {  }  public int getType() {    return type;  }  public void setType(int type) {    this.type = type;  }  public String getMsg() {    return msg;  }  public void setMsg(String msg) {    this.msg = msg;  }  public String getKeyIP() {    return keyIP;  }  public void setKeyIP(String keyIP) {    this.keyIP = keyIP;  }  public String getTemporaryIP() {    return temporaryIP;  }  public void setTemporaryIP(String temporaryIP) {    this.temporaryIP = temporaryIP;  }}
