A program, enter 10 integers, and put in the array, first descending output all the number, and then statistics and output the number of positive, negative and zero

Add ( -1); List.add ( -2); List.add ( -4); List.add (0); List.add (2); List.add (5); List.add (9); List.add (7); List.add (-9); List.add ( -7); int num1 = 0;//Indicates the number of positive numbers int num2 = 0;//Indicates the number of negative numbers int num3 = 0;//represents the number of 0 for (int i=0;i<list.size (); i++) {if (list). Get (i) >0) {num1++;} else if (List.get (i) <0) {num2++;} else{num3++;}} System.out.println ("Number of positive numbers:" +num1+ "number of negative numbers:" +num2+ "is the number of 0:" +num3);}}
