Inputer is a simple, easy-to-use, well-documented class for prompting for and validating input from the command line.
See InputerPlay.java for usage examples. The basic syntax is:
String name = Inputer.getString("Enter your name");
Inputer will add ": " to a prompt that it thinks needs it. So the above prompt would actually be:
Enter your name:
Validation is done with predicates. For instance, this would get a positive integer:
int number = Inputer.getInt("Enter a positive integer", i -> i > 0);
Some predicates are provided for you. For instance, the following will return "m", "f", or "t":
String gender = Inputer.getString("Enter gender (m/f/t) ", Inputer.oneOfThese("m", "f", "t"));
A specialized version of the above is used to easily a yes/no response. This can be used in loops:
do {
// Get data here
} while (Inputer.getYN("Is this correct?") == 'n');
- Make class more DRY
- Does not work with BigInteger or BigDecimal
