GANNOUNI & Dr. A. TOUIR Introduction to OOP The Nested-for Statement • Nesting a for statement inside another for statement is commonly used technique in programming. • Let’s generate the following table using nested-for statement.

TOUIR Introduction to OOP Generating the Table int price; for (int width = 11; width <=20, width++){ INNER OUTER for (int length = 5, length <=25, length+=5){ price = width * length * 19; //\$19 per sq. ft. System.out.print (“ “ + price); } //finished one row; move on to next row System.out.println(“”); } Page 17 Dr. S. GANNOUNI & Dr. A. TOUIR Introduction to OOP...
