3. Consider how a Java program reads input from the keyboard. O O Give three methods from the Scanner class that you can use to read input from the keyboard with Scanner sc = new Scanner(System.in); Which method is used to read an integer with the scanner sc in 3a? Can you use the Scanner class to read an integer twice from the keyboard with the method you identified in 3b? If so, give the code that will allow that to happen. If not, explain what your program should do to use that word multiple times. When mixing Scanner methods in a program (i.e., calling different methods consecutively), which Scanner method will appear to read nothing from the keyboard if following another Scanner method? (If you do not know, put a question mark and move on). Consider what happens when your Java program writes output to the monitor (console). Give two methods that you can use to write output to the monitor.
