我制作了一个程序,用于在本地网络位置显示IP,网络名称和DNS查找。这是获取所有地址的代码:
public void NetworkPing() throws Exception{
jlist.clear();
jlist2.clear();
jlist3.clear();
InetAddress localhost = InetAddress.getLocalHost();
byte[] ip = localhost.getAddress();
for(int i=1;i<254;i++){
ip[3]=(byte)i;
InetAddress address = InetAddress.getByAddress(ip);
if(address.isReachable(1000)){
jlist.addElement(address); //Machine is turned on and can be ping.
}else if(!address.getHostAddress().equals(address.getHostName())){
jlist2.addElement(address); //Machine is known in a dns lookup.
}else{
jlist3.addElement(address); //The host address and host name are equal, meaning the host name could not be resolved.
}
final DefaultListModel jlist1 = jlist;
this.jList1.setModel(jlist1);
final DefaultListModel jlisttwo = jlist2;
this.jList2.setModel(jlisttwo);
final DefaultListModel jlistthree = jlist3;
this.jList3.setModel(jlistthree);
}
}
此过程需要一些时间才能完成并完全显示到JList。我只想为用户添加一个进度条,以了解完成了多少百分比以及用户如何等待完成所有过程......
我的问题是,如何将进度条与上述代码结合起来?
非常感谢任何帮助。谢谢。
