public static String inputString ()
{
Scanner scan = new Scanner (System.in); // attach to console
return ( scan.next() ); // return next string from input console stream
}
Consider that the only console input method using the Scanner class is inputString(), ( Shown above) include this in your solution.
Note: You are not permitted to use the Scanner class in any of your methods.
Example of calling and testing this method in your main():
String str = inputString(); // get input from console, assign to str
displayln ("Input A is: " + str); // display input string
displayln ("Input B is: " + inputString() ); // get input and display
Implement the following static methods, and include statements to test each (such as the example above).
Input method headers:
1. public static int inputInt () – inputs an int from the consle
2. public static double inputDouble () – inputs a double from the console
3. public static char inputChar () – inputs a single char (character) from the console
4. public static boolean inputBool () – inputs a boolean values (true, false)
Combo prompt & input method headers:
5. public static int inputInt (String prompt) – displays the prompt to the console, and inputs an int
6. public static int inputDouble (String prompt) – displays the prompt to the console, and inputs a double
Example:
double val = inputDouble ("Enter a value: "); // display prompt ("Enter a value" and get input
displayln ("Input C is: " + val); // display input value
Hints:
- don't forget the String methods, and wrapper class methods (Integer.parseInt(), Double.parseDouble(), … ) to convert from String to other data types
- apply the concept of overloading, and that the methods can call inputString(), or each other, to reduce repeating code
Provide :
- include a call for each method in your main() method and display the inputted value.
