我想要一个类似vc中的ip控件的一个类,实现ip的格式输入.~~~高分

多谢!提供思路也可以! 我有的是分数噢!!

对输入的VALUE，做CHECK喽！

public long getDecimalfromIP(String addr)
{
StringTokenizer st = new StringTokenizer(addr,".");
long n1 = Integer.parseInt(st.nextToken());
long n2 = Integer.parseInt(st.nextToken());
long n3 = Integer.parseInt(st.nextToken());
long n4 = Integer.parseInt(st.nextToken());
long ret = 0xFFFFFFFF & ((n1 << 24) | (n2 << 16) | (n3 << 8) | n4);
return((long)ret);
}

public String getIPfromDecimal(long ip)
{
String s1 = new String(new Long((long)(ip >> 24) & 0xFF).toString());
String s2 = new String(new Long((long)(ip >> 16) & 0xFF).toString());
String s3 = new String(new Long((long)(ip >> 8) & 0xFF).toString());
String s4 = new String(new Long((long)ip & 0xFF).toString());
return(new String(s1 + "." + s2 + "." + s3 + "." + s4));
}
