Question

Hello,

Please help write program in JAVA that prints out the Multiplication Table for a range of numbers (positive integers).

PROGRAM MUST DO THE FOLLOWING:

1) Prompt the user for a starting number: 'x'

2) Prompt the user for an ending number: 'y'

3) Print out the multiplication table of 'x' up to the number 'y'

SPECIFIC REQUIREMENTS

1) You must use the following method to load the array: public static void loadArray(int table[ ][ ], int x, int y)

2) You must use the following method to display the array: public static void printMultiplicationTable(int table[ ][ ], int x, int y)

3) You must load the table array with products of the factors. See screenshot of working program below:

In Figure 1 below, the 5 x 5 array is loaded with the products for the times tables from 5 to 8

In Figure 2 below, the 2 x 2 array is loaded with the products for the times tables from 5 to 6

4) Code must be properly commented

CA. C: WindowsAsystem320cmd.exe Enter the starting value Enter the ending value 4 16 20 24 28 32 5 20 25 30 35 40 6 24 30 36 42 48 28 35 42 49 56 8 32 40 48 56 64 Press any key to continue Figure 1 CA. C:Windowslsystem32lcmd.exe Enter the starting value Enter the ending value 5 6 5 25 30 6 30 36 Press any key to continue Figure 2

Explanation / Answer

/**

   }
  
   /**

   public static void printMultiplicationTable(int table[ ][ ], int x, int y){
       //starging lines
       System.out.printf("     ");      
       for (int i = 0; i < y; i++) {
           System.out.printf("%-4d",x+i);
       }
       //for dashed heading
       char ch='-';
       System.out.printf(" -------------");
       for (int i = 0; i < 4*x; i++) {
           System.out.printf("%c",ch);
       }
       System.out.println();
       //print rows and columns of table
       for (int row = 0; row < table.length; row++) {
           System.out.printf("%-4d |",x+row);
           for (int col = 0; col < y; col++) {
               System.out.printf("%-4d",table[row][col]);                          
           }
           System.out.println();          
       }  
   }
  
   /**
   * The method loadArray takes two 2d table array and
   * starging x and ending y values
   * and stores the multiplication values of x and y
   * into table array
   * */
   public static void loadArray(int table[ ][ ], int x, int y){
       //for row values
       for (int row = 0; row < table.length; row++) {
           //for column values
           for (int cols = 0; cols < y; cols++) {
               //set product to table
               table[row][cols]=(x+row)*(x+cols);

       }
   }
}
