desending sort algo

... double []test = new double []{88.6,88.9,-1,25,88.6}; int size = test.length; System.out.println("*** un-sorted ***"); for (double d : test){ System.out.println(d); } // descending sort algo ************************************* int counter = 0; int indexOfMax = 0; // after each iteration of while, test[counter] should have the correct value while (counter < size){ indexOfMax = counter; // assuming that test[counter] has the max value // this loop finds the index of max value (stores in indexOfMax) from the test array starting from index counter+1 for(int i = counter+1; i < size; i++){ if (test[i]>test[indexOfMax]){ indexOfMax = i; } } // end of for loop -- now indexOfMax should have the max value // swapping double tmp = test[counter]; test[cou

Comparable interface

Lists and Arrays of objects that implement Comparable interface can be sorted automatically by Collections.sort and Arrays.sort respectively. Implementation Comparable is easy. You just have to implement compareTo(Object o). It should return negative integer, zero, or a positive integer as this object is less than, equal to,or greater than the specified object. Here goes an example: public void testListSort(){ Calendar cal = Calendar.getInstance(); cal.set(2010, 10, 1); License msWindows7 = new License("Windows", "7",new Date(cal.getTimeInMillis())); cal.clear(); cal.set(2010, 11, 10); License msWindowsVista = new License("Windows", "Vista", new Date(cal.getTimeInMillis())); cal.clear(); cal.set(2010, 11, 5); License lotusNotes = new License("Notes", "1.1", new Date(cal.getTimeInMillis())); List list = new ArrayList (3); list.add(lotusNotes);
