yo are right indeed..! solving with created functions gives no good..my java code is really big but understandable.. { Scanner sc=new Scanner(System.in); int a=sc.nextInt(); double mean; int[]arr=new int[a]; for(int i=0;i

 }
          int sum=0;
         //mean
          for(int i=0;i<a;i++)
              {
              sum=sum+arr[i];
          }
          mean=(double)sum/a;
        //median
          Arrays.sort(arr);
          double median;
          int A=arr.length;
          if(A%2==1)
          {
            median=arr[(A-1)/2];
          }
          else{
              int c,d;
              c=arr[(A-1)/2];
              d=arr[((A-1)/2)+1];
              median=(double)(c+d)/2;
          }
          //mode
          int mode=0; int itr; int count;  int max=0;
          for(int i=0;i<a;i++)
       {
           itr=arr[i];
           count=0;
          for(int c=0;c<a;c++)
          {
          if(itr==arr[c])
          {count++;}
          if(count>max)
           {  max=count;
              if(max==1)
                  {
                  mode=arr[0];
                  }
             mode=itr;
                }
          }           
       }
          System.out.println(mean);  
          System.out.println(median);
          System.out.println(mode);

    }
