Could anybody answer this question?

Complete the implementation of the constructor and the methods, run and toString.

constructor
?	accepts a parameter size
?	instantiates anarray of length size
?	declares a random object
?	uses the random object to fill the array

run( )
?	declares a variable to store the maximum value in the array
?	examines the array using Math.max to determine the largest value
?	displays "Max value is" and the value of max

toString( )
?	returns a String "Array contents" followed by a list of numbers in
the array, seperated by spaces

Example output
Array contents - -171976890 -837367250 588580956 1404222675 -254609160
1878654740 -16822294198 1602621976 -556422055 334633135
Max value is 1878654740

Examq4.java

public class Examq4   {
    private int[]a;
    
    public Examq4(int size)   {
        



    }

    public void run( )   {
        int max;




    }

    public String toString( )   {
        String result = "Array contents";



        return result;
    }

    public static void main(String[] args)   {
        Examq4 q4 = new Examq4(10);
        System.out.println(q4);
        q4.run( );
    }
}

Hi cb153-ga thanks for giving me chance to answer your question here
is the completed implementation

import java.util.*;

public class Examq4{

        private int[]a;

        int n;
        public Examq4(int size){

        int i;
        a = new int[size];
        Random rand = new Random();
        for(i=0;i<size;i++)
        {
        a[i]=rand.nextInt();
        }
        n=a.length;
        }


        public void run()
        {
         int max;
         if(n!=0)
         {
         max=a[0];
         for(int i=1;i<n-1;i++)
         {
         max=Math.max(max,a[i]);
         }
         System.out.println("Max value is "+max);
         }

        }


        public String toString()
        {             
          int i;
          String result="Array contents:";
          if (n!=0)
          {
          for(i=0;i<n;i++)
          {
          result+=" "+a[i];
          }}
          else
          result+=" Empty";
          return result;
        }

        public static void main(String args[]) 
        {
         Examq4 q4=new Examq4(10);
         System.out.println(q4.toString());
         q4.run();
         }
         
        }
