    I cannot get the correct Average using Random Generator method

    Create an array that will store 7 temperatures.
    Populate the array with 7 random temperatures from 1 to 100 degrees. (hint use a for loop and a Random number Generator)
    After the temperatures are in the array, calculate the average of the temperatures in the array.
    Print out the average.
    Print out each temperature in a statement comparing it to the average such as:
    The average temperature is 48.94

    Temperature 1 is 5.0 and is below average.

    Temperature 2 is 67.8 and is above average.


    Code:
    import java.util.Random;
    
    public class ArrayOfTemperatures
    {
       public static void main(String[] args)
       {
          // Declare an array
          int[] randomtemps = new int[7];
          temps[0] = 45;
          temps[1] = 32;
          temps[2] = 55;
          temps[3] = 75;
          temps[4] = 89;
          temps[5] = 42;
          temps[6] = 25;
       
       // record temperatures and find average
          int counter = 0;
          for (int i = 0; i < temperature; i++)
          {
             temps[i] = random.nextInt();
             counter++;
          }
          double average = (double) counter / temperature;
       
        // count days
          int above = 0;
          for (int i = 0; i < temps.length; i++)
          {
             if (temps[i] > average)
             {
                above++;
             }
          }
       
       // report results
          System.out.println();
          System.out.println("Average = " +  average);
          System.out.println(above + " days average");
       }
    }

    Does that code compile? I don't see where the variable: temperature is defined.
