Question

This is a very simple program that will ONLY print a heading and columns of text to emulate the following information:

Sales This Month	Admin Fee	Commission Rate
----------------------------------------------	----------------------------------------------	----------------------------------------------
Less than $10,000	$150	5%
$10,000 – 14,999	$150	10%
$15,000 – 17,999	$150	12%
$18,000 – 21,999	$200	15%
$22,000 or more	$200	16%

******Salesperson of the month******

Name: STUDENT NAME

ID: STUDENT ID

public class SalesResult {

public static void main(String[] args) {

System.out.println();

. . .

}

}

Create a Java project in Eclipse named SalesProject and add a class named SalesResult to reproduce a table like the above. In your program repeat the System.out.println(); as many times as needed.

I was wondering how to write the code to create such a table...

//------------ SalesResult.java -------------------

public class SalesResult
{
   public static void printLine()
   {
       System.out.println("______________________________________________________________________");
   }
   public static void main(String[] args)
   {
       //headers for table here mention your headers
       String[] headers = {"Sales This Month" , "Admin Fee" , "Commission Rate"};
       //create a table of contents to be displayed
       //here mention your table rows.
       //NOTE: IF YOU GIVE MORE COLUMNS THAN THE HEADERS LENGTH
       //FIRST HEADER LENGTH COLUMNS WILL BE CONSIDERED.
       //EXAMPLE HERE HEADERS LENGTH IS 3, IF I INCLUDE > 3 COLUMNS IN
       //MY ROWS THEN FIRST 3 WILL BE CONSIDERED
       String[][] table = {
           //ROWS.
           {"Less than $10,000" , "$150" , "5%"},
           {"$10,000 – 14,999" ,"$150" ,"10%"},
           {"$15,000 – 17,999" , "$150" ,"12%"},
           {"$18,000 – 21,999" , "$200" ,"15%"},
           {"$22,000 or more" , "$200" ,"16%"}
       };
      
      
      
       System.out.println();
       int i,j;
       //length is the total columns or headers int table.
       int length = headers.length;
      
       //printLine() for printing a horizentol line
       printLine();
       //print headers
       System.out.print("\n");
       for(i = 0 ;i<length;i++)
       {
           System.out.print(String.format("| %-20s ",headers[i]));
       }
       //print closing | for row.
       System.out.println("|");
       //print line
       printLine();
      
       System.out.println();
       //print dashes like in the given table for
       //since there are length columns we have to print those many dashes columns.
       for(i=0;i<length;i++)
       {
           System.out.print(String.format("| %-20s ","-----------------"));
       }
       //print closing | for row.
       System.out.println("|");
      
       //print dashes like in the given table for
       //since there are length columns we have to print those many dashes columns.
       for(i = 0;i<length;i++)
       {
           System.out.print(String.format("| %-20s ","--------------"));
       }
       //print closing | for row.
       System.out.println("|");
       printLine();
      
       //now get number of rows.
       int rows = table.length;
       for(i = 0;i<rows;i++)
       {
           //print first length columns of i_th row .
           System.out.print("\n");
           for(j = 0;j<length;j++)
           {
               System.out.print(String.format("| %-20s ",table[i][j]));
           }
           //print closing | for row and horizentol line.
           System.out.println("|");
           printLine();
       }
       System.out.println("\n****** Salesperson of the month ******\n");
      
   }
}
