Complicated JAVA writing algorithm questions HELP!

Complicated JAVA writing algorithm static void Q13(ArrayList<Integer> input){//sort the input ArrayList in increasing order} static double Q14(ArrayList<Integer> input){//return the median value of the input ArrayList. If the size is even, return the average of the two//elements closests to the median return 0.0;} static int Q15(ArrayList<Integer> input){//return the mode value of the input ArrayList. Ties can be broken arbitrarily return 0;}

Answer: Source code: import java.util.*; public class Arrayclassf static void 213 (ArrayList<Integer> Input) Collections.sort (Input); system.out.println (Input); static double Q14 (ArrayList<Integer> Input) int mide 1 = Input. size() /2; if (input . size ( ) % 2-0) { return 0.5 (Input.get (midel).doubleVvalue() -+ Input.get (midel-1) .doubleValue ()) else return Input.get (midel).doubleValue )

static int 915 (ArrayList<Integer> Input) int mode0 int c-0, x, y,temp; for int i- 0 i< Input.size) i+) xInput.get (i); temp l; for ( int e = 0; e< Input. Size() ; e++ ){ y -Input.get (e); if ( x-y) temp++ if ( temp > c) c temp; modeXi

return mode public static void main (String [largs) ( ArrayList<Integer> list-new ArrayList<Integer; Scanner anew Scanner (System.in); int n-a.nextInt )i int xi for (int i-0 i<n i++) x=a. next int ( ) ; list.add (x) ystn.out.printin (Array ist in sorted orderr Q13 (list) System.out.println ("Median of the array list is "+914 (list)); system.out.println ("Mode of the array list is "+Q15 (list))

Sample Output: 5 2 4 5 2 Array List in sorted order [2, 2, 4, 5, 6] Median of the array list is 4.6e Mode of the array list is 2 sh-4.3$
