高手入，求一循环判断的解决办法

ID         UP
14         12
15         14
20         15
16         15
30         16
31         16
35         16

judge( "14 ", "35 "),例如，依据ID14得到UP=14的ID15，再依据UP=15的ID20得到UP=20的空记录，和UP=15的ID16得到ID30，ID31，ID35。查到35后judge()返回true,反之则是false。该怎么写循环判断，求高手解答，急需！！

------解决方案--------------------
private static boolean judge(String ID,String UP){

String[][] test = new String[][]{
{ "14 ", "15 ", "20 ", "16 ", "30 ", "31 ", "35 "},
{ "12 ", "14 ", "15 ", "15 ", "16 ", "16 ", "16 "}
};

if(ID.equals(UP))return true;
for(int i=0;i <test[1].length;i++){
if(test[1][i].equals(ID)){
String check = test[0][i];
if(check.equals(UP))return true;
boolean rtn = judge(check,UP);
if(rtn)return true;
}
}

return false;
}
