Question

Name your Java project  LoopControl and the Class name as LoopControl

Firs line of program    // LoopControl by  your name

First line of output to console  System.out.println(“LoopControl by  your name”);

Use <for > loop  and <if..else>   branch to do your program

1.Fill an Integer array with random numbers (0-10)

Use  Array definition int[] numbers= new double[10]; //define an array <numbers>

use   numbers[i]=Math.random()*10 +1; //to Fill array with random numbers

// NOTE: Math.random() is a double but   <numbers> is an integer

Output to console all the elements of <numbers> array, one element per line

2,Sum the values of all the elements of the <numbers> array and output this value to the console   System.out.println(“Sum= “+ sum);

3,Find the average (double variable) of the array elements in <numbers> and output to console to nearest hundredth.

4,Find the Maximum value of element in this array and output value to the console, nearest tenth

Use <for> loop and   <if…else> for your processing.   Remember about casting.

   You may use more than one <for> loop (one to set array[i] values, one to find the  Max and average values of  <numbers[i]> , however it can be accomplished with one loop

Explanation / Answer

LoopControl.java

public class LoopControl {

   public static void main(String[] args) {
       // LoopControl by your name
       int sum=0;
       double average=0.0;
       System.out.println("LoopControl by your name");
      
       int[] numbers= new int[10];
         
       //generating random numbers and populating those values into an array
       for(int i=0;i<numbers.length;i++)
       {
           numbers[i]=(int)(Math.random()*10 +1);
       }

       //Displaying the elements in the array
       System.out.println("Displaying the elements in the array :");
       for(int i=0;i<numbers.length;i++)
       {
           System.out.println(numbers[i]);
           sum+=numbers[i];
       }
         
       //Displaying the sum
       System.out.println("Sum= "+ sum);
         
       //calculating the average
       average=((double)sum)/numbers.length;
         
       //Displaying average
       System.out.printf("Average = %.2f ",average);
         
       //Calling Method to Find maximum element
       int max=findMax(numbers);
System.out.println("The Maximum Element is :"+max);
     
   }

  
   //Method to Find maximum element
   private static int findMax(int[] numbers) {
       int max=numbers[0];
       for(int i=0;i<numbers.length;i++)
       {
           if(max<numbers[i])
           {
               max=numbers[i];
           }
       }
       return max;
   }

}
