Question

Write a method named printGrid that accepts two integer parameters rows and cols. The output is a comma-separated grid of numbers where the first parameter (rows) represents the number of rows of the grid and the second parameter (cols) represents the number of columns. The numbers count up from 1 to (rows x cols). The output are displayed in column-major order, meaning that the numbers shown increase sequentially down each column and wrap to the top of the next column to the right once the bottom of the current column is reached. Assume that rows and cols are greater than 0.

Here are some example calls to your method and their expected results:

Call:	printGrid(3, 6);	printGrid(5, 3);	printGrid(4, 1);	printGrid(1, 3);
Output:	1, 4, 7, 10, 13, 16 2, 5, 8, 11, 14, 17 3, 6, 9, 12, 15, 18	1, 6, 11 2, 7, 12 3, 8, 13 4, 9, 14 5, 10, 15	1 2 3 4	1, 2, 3

Method problem: For this problem, you are supposed to write a Java method as described. You should notwrite a complete Java class; just write the method(s) described in the problem statement.

Answer 1

The follwoing is the required method as per the requirments

Method:

public static void printGrid(int r,int c) int count=0; for (int i=1;i<=r ;i++) coun t=1 ; for (int j-1:jK c:j++) System.out.print (count) if (j !=c) System.out.print(", "): count=count+ r; System.out.println

Sample output:

Enter the size of the grid 3 6 h, 4, 7, 10, 13, 16 2, 5, 8, 11, 14, 17 3, 6, 9, 12, 15, 18

Enter the size of the grid 4 1 2 4

Code to copy:

public static void printGrid(int r,int c)

     {

          int count=0;

         

          for(int i=1;i<=r;i++)

          {

              count=i;

              for(int j=1;j<=c;j++)

              {

                   System.out.print(count);

                   if(j!=c)

                        System.out.print(", ");

                  

                   count=count+ r;

                  

              }

              System.out.println();

          }

         

         

     }

Answer 2

publicstaticvoidprintGrid(intiRows,intiCols)
{
StringBuildersb=newStringBuilder();
for(intr=1;r<=iRows;++r)
{
for(intc=1;c<=iCols;++c)
{
if(c>1)
{
sb.append(",");
}
sb.append((iRows*(c-1))+r);
}
sb.append("\n");
}

System.out.println(sb.toString());
}
