How can I build histogram using arrays in java?

Take input from user in an array in form of numeric and show histogram Where i'm wrong The code is given in java the user can enter 5 input in number and histogram should show in any form with no constraints

    package p21;
    import java.util.Scaer;

    public class P21 {
    public static void main(String[] args) {
    {
    int count[]=new int[10];  // count array will keep elements of element
                              // in particular range;
     int elements[];       // for example   27 15 34 22 11 11 19
    {                                  // in above input there is count[0]=0;
     for(int i=0;i<elements.length;i++)   // count[1]=4 and count[2]=2 and count[3]=1;
    {
     if(elements[i]>=0 && elements[i]<50)
    {
      if(elements[i]<10)
     {
      count[0]++;
      }
      else if(elements[i]>=10 && elements[i]<20)
      {
       count[1]++;
      }
      else if(elements[i]>=20 && elements[i]<30)
      {
       count[2]++;
      }

   }}
    else if(elements[i]>=50 &&elements[i]<=100)
   {
   if(elements[i]<60)

      count[5]++;
   }

    {

    }

   {                                // at each line.
       System.out.print("* ");
   }
   if(count[i]!=0)                  // if line does'nt contain zero   
   System.out.println("");          // then if will change the row;
   }}}
   /*
   in above code if count[i]=zero means if there is elements
   element in particular range say [0-9] then it will
   elementst jump on next line;
