public static String[] splitStringByComma(String source){
if(source ==null||source.trim().equals(""))
return null;
StringTokenizer commaToker=new StringTokenizer(source ,",");
String[] result=new String[commaToker.countTokens()];
int i=0;
while (commaToker.hasMoreTokens()) {
result[i] = commaToker.nextToken();
i++;
}
return result ;
}
public static void main(String args[]){
String[] s=splitStringByComma("5,8,7,4,3,9,1");
int[] ii=new int[s.length];
for (int i = 0; i < ii.length; i++) {
ii[i]=Integer.parseInt(s[i]);
}
Arrays.sort(ii);
for (int j = 0; j < ii.length; j++) {
System.out.println(ii[j]);
}
for (int i=(s.length-1);i>=0;i--){
System.out.println(ii[i]);
}
}
}
