IllegalStaffNameArgumentException

public class IllegalStaffNameArgumentException extends IllegalArgumentException { public String noStaff; public IllegalStaffNameArgumentException(String nameS) { if (nameS == null) noStaff = "Staff cannot be named null"; else if (nameS.isBlank()) noStaff = "Staff name cannot be blank."; else if (nameS.isEmpty()) noStaff = "Staff name cannot be empty."; } public String toString() { return this.getClass().getSimpleName() + " : " + noStaff; } }

test2.java

 public class test2 { public static void main(String[] args) { try { test2 IllegalStaffNameArgumentException= new test2(); } catch (IllegalStaffNameArgumentException i) { System.out.println(i.toString()); }catch (IllegalArgumentException i2) { System.out.println("Exception has been caught: IllegalArgumentException"); } } }
