sorting integers in order lowest to highest java

Question

These numbers are stored in the same integer variable. How would I go about sorting the integers in order lowest to highest?

11367
11358
11421
11530
11491
11218
11         


        

Answer 1

You can put them into a list and then sort them using their natural ordering, like so:

final List list = Arrays.asList(11367, 11358, 11421, 11530, 11491, 11218, 11789);
Collections.sort( list );
// Use the sorted list

If the numbers are stored in the same variable, then you'll have to somehow put them into a List and then call sort, like so:

final List list = new ArrayList();
list.add( myVariable );
// Change myVariable to another number...
list.add( myVariable );
// etc...

Collections.sort( list );
// Use the sorted list

• Collections.sort( List )
