Medications can include: 1  Antibiotic medications to kill H. pylori. If H. pylori is found in your digestive tract, your doctor may recommend a combination of antibiotics to kill the bacterium. 2  Medications that block acid production and promote healing.
Most times, though, we want to say how many decimal places to print and, sometimes, how many columns to use. For example, if we want to print d, above, to 2 decimal places in a field width of 6, we can use: System.out.printf(%6.2f \n, d); Between % and f, we write 6.2, that is, the field width, followed by a . (point), followed by the number of decimal places.
The values that they return are displayed on the right, int and void. Because the print_text method is a void method, you don't need to set up a return value. All you need is the name of your object, a dot, and the void method you want to call. Java will then just get on with executing the code inside of your method.
