in Java please use only while loops.

Based on nested while loops, write a program that will cycle through an imaginary seven rows (1 through 7) and six columns (A through F) to produce the output shown below. For the output, indicate what row and column is referenced—along with the product of the row multiplied by the ASCII code for the letter of the column. This is a totally useless, arbitrary thing to do. The product of the ASCII codes has no special meaning; it\'s just practice to get the code to do it. Use a void() method to produce each line of output. Pass the method the current row and column; have the method calculate the product (row x col) and display it as shown below. Your row counter variable is pretty straightforward—it will need to be an int and it will range from 1 to 7. Columns are a little trickier but this should make it simple: recall, characters are stored internally as int values (ASCII codes) so addition and subtraction works against the underlying ASCII value if you cast your fishing line appropriately. Example output

Row 1 Col A: 65

Row 1 Col B: 66

Row 1 Col C: 67

Row 1 Col D: 68

Row 1 Col E: 69

Row 1 Col F: 70

Row 2 Col A: 130

Row 2 Col B: 132

Row 2 Col C: 134

…
…

Row 6 Col C: 402

Row 6 Col D: 408

Row 6 Col E: 414

Row 6 Col F: 420

Row 7 Col A: 455

…

Row 7 Col F: 490

Solution

/**

public class GenerateCycle {

   /**
   * @param args
   */
   public static void main(String[] args) {
       int i = 1;
       while (i <= 7) {
           char ch = \'A\';
           while (ch <= \'F\') {

               System.out.println(\"Row \" + i + \" Col \" + ch + \": \"
                       + calculate(i, ch));
               ch++;
           }
           i++;
       }
   }

   /**
   * @param row
   * @param col
   * @return
   */
   public static int calculate(int row, int col) {

       return row * col;

   }
}
