IHow do you refractor this:

Question

public class Employee {
private boolean isPartTime;
private int seniority;
private int monthsDisabled;

public Employee(boolean isPartTime, int seniority, int monthsDisabled) {
this.isPartTime = isPartTime;
this.seniority = seniority;
this.monthsDisabled = monthsDisabled;
}

// TODO: add a function here with the signature: public boolean notEligibleForDisibility()

public double disabilityAmount() {
// TODO: replace these checks with a single function call
if (seniority < 2)
return 0;
if (monthsDisabled > 12)
return 0;
if (isPartTime)
return 0;

// in a real program, there would be other logic for determining
// the amount of disability the employee is eligible for here
