    The images you originally supplied link to a site that contains pornographic advertisements. That's not great, as some of us are at work, and some of us have wives and stuff.

    If you want to post code, post the text, not an image. Use the code tags and post an SSCCE. Don't post screenshots of your code. Same goes with error messages or stack traces.

    so this is the coding for what i have done . still cant get what i want .
    import java.util.*;
    class  lab1{
            public static void main(String[] args){
            int sum=0,count=0;
            Scanner input=new Scanner(System.in);
            System.out.println("Enter a Number: ");
            int array[]=new int[10];
            for(int i=0;i<array.length;i++){
                int num=input.nextInt();
                array[i]=num;
            }
            int maxValue = array[0];
            for(int i=1;i < array.length;i++){
            if(array[i] > maxValue){
            maxValue = array[i];
            }
            }
            for(int i=0;i<array.length;i++){
                sum+=array[i];
                if(array[i]==maxValue){
                    count++;
                }
            }
            System.out.println("Total Of Numbers is: "+sum);
            System.out.println("Average of Numbers is: "+sum/array.length);
            System.out.println("Largest No: "+maxValue+" which occurs "+count+" times.");
            Arrays.sort(array);
            System.out.println("Numbers in ascending order: ");
            for(int i=0;i<array.length;i++){
              System.out.println(array[i]);
            }
            System.out.println("Numbers in descending order: ");
            for(int i=array.length-1;i>=0;i--){
              System.out.println(array[i]);
            }
        }
    }

    When posting code, make sure you use the highlight tags. I've added them for you this time.

    But your whole problem is that you're using ints, which are only whole numbers (0, 1, 2, not 1.5 or 2.3). That's fine for things that are only whole numbers (counts of things, indexes, etc), but if you want to have decimals (for things like averages), you have to use double or float.

    Note that you do not have to convert all your variables to double if it doesn't make sense. All you need to do is cast your sum to a double when doing the calculation.
     System.out.println("Average of Numbers is: " + (double)sum/array.length);
