Loop the for and Nested-for statements - An example code of Java to multiply numbers

The for and Nested-for statements can be gathered in multiply way, it is usually building the for statement into another for statement in the case of ( Nested-for statements ), but in Syntax for the for statement it is easier to use and initialize or add increment as follows. 

.
for( initialization; boolean expression; increment, decrement or update)
 {
   Statement here .......
   }




Now this is another example to multiply numbers in the shape of multiplication table to Nested-for statements, because we have to add columns and rows, so two or three the for statement in one not matter, it depends on the programmer.

public class columnsAndRows
{
    public static void main(String[]args)
    {
        System.out.println("Multiply numbers");
        System.out.println("----------------");
        for (int rows =1; rows <= 10; rows++) // Ten rows
        {

            for (int columns = 1; columns <= 6; columns++) // Nine columns
            {
                System.out.print(rows*columns + ", "); // Multiply row by columns and print them as one
                                                                          // line has 5 column
            }
            System.out.println(" ");  // To print 10 rows in print line
        }
    }
}

You have to know that we printed first columns after Multiplying them and add them in ( System.out.print ), That meant do not jump or print them in a new line, then we added (System.out.println(" ")) as lines with space.  You may want to know that we added each one of these ( prntln And print ) with their correct for statements.

This is the output of the program
