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.
Suppose you are printing n= 18999 with printf(%2d,n) then it will reserve the output console with 2 character and if the number of digits of n are larger than the specifier then it will print with no spaces, now suppose you print with %6d then what will happen the number of character it will reserve i.e. 6 now number of digits in n is 5 so it will print with after 1 character on the console printing with 1 space in %8d then leaving 3 spaces and then the number n.
