JAVA中把长整型转换为IP地点的要领

代码如下：

/** 
 * 整型解析为IP地址 
 * @param num 
 * @return 
 */
public static String int2iP(Long num)   
{  
    String str = null;  
    Long[] tt = new Long[4];  
    tt[0] = (num >>> 24) >>> 0;  
    tt[1] = ((num << 8) >>> 24) >>> 0;  
    tt[2] = (num << 16) >>> 24;  
    tt[3] = (num << 24) >>> 24;  
    str = (tt[0]) + "." + (tt[1]) + "." + (tt[2]) + "." + (tt[3]);  
    return str;  
}
