java - Creating an algorithm that can sort string/integer arrays -

i trying figure out how make sorting function sort array in descending order.

public void dsort(string field) throws datasetexception {     int front = 0;     int findex = -1;      string[] tosort = new string[50];     (int = 0; < filedata[0].length; i++) {         if (field.equalsignorecase(filedata[0][i])) {             findex = i;         }     }     if (findex == -1) {         throw new datasetexception();     } else {         (int k = 0; k < getnumrecords(); k++) {             if (filedata[k][findex] != null) {                 tosort[front] = filedata[k][findex];                 front++;             }         }         comparator comparator = collections.reverseorder();         arrays.sort(tosort, comparator);         system.out.println(arrays.aslist(tosort));     } } 

what creates new array taking elements array of arrays, want do. however, output of sort 32, 3, 25, 20, 2, 1000, 1 etc.. these "integers" considered strings, , sorting function supposed able sort words strings. think should trying use comparable, unsure of how implement in situation.

if number, don't want store them string, store them numbers , use numeric sort.

if on other hand, have combination of strings, of numeric, , of alphabetic, i'd recommend using alphanumcomparator, available here
