Before starting please go through Test cases provided.
You can create your Validator with POJO
class Model {
private String firstName;
private String lastName;
private Integer age;
private Integer Salary;
//Assume all getter setter methods here
public static Validator<Model> validator = Validator.stream(Model.class)
.add(Model::getFirstName, Validator.REQUIRED | Validator.UPPERCASE, "First name is required and to be uppercase")
.add(Model::getLastName, Validator.LOWERCASE, "Last name required to be lowercase")
.min(Model::getFirstName, 5, "First name is invalid")
.max(Model::getLastName, 10, "Last name is invalid")
.max(Model::getAge, 55, "Employee age limit is reached")
.min(Model::getSalary, 10000, "Salary can't be less than 10000")
.in(Model::getLastName, Arrays.asList("Larry", "Moe", "curly"), "Last name is not expected")
.notIn(Model::getFirstName, Arrays.asList("Thonas", "Loki"), "You are villan")
.check(Model::getLastName, l -> l.startsWith("c"), "Last name is not C.lassy");
}
#Lets talk about functions by Validator
- add(): you can add here checks(ALPHABETIC, ALPHANUMERIC, NUMERIC, UPPERCASE, LOWERCASE, REQUIRED, EMAIL) with
oroperator - min(): you can check min for String and Integer values
- max(): you can check max for String and Integer values
- in(): you need to provide list and check given value is provided in list.
- notIn(): you need to provide list and check given value is provided not in list.
- check(): you can provide your own Predicate function and say validate using this.
Model m = new Model();
m.setFirstName("Greta");
m.setLastName("Thunderburg");
m.setAge(60);
m.setSalary(9000);
Model.validator.test(m) //Returns True or False
Model.validator.getErrors() //Returns Errors List
Use Check class for other validations
