Question

Leap Years. Write a method public static boolean isLeapYear(int year) that tests whether a year is a leap year: that is, a year with 366 days. Exercise P3.28 describes how to test whether a year is a leap year. In this exercise, use multiple if statements and return statements to return the result as soon as you know it.

Explanation / Answer

public static boolean isLeapYear(int year) { Calendar cal = Calendar.getInstance(); cal.set(Calendar.YEAR, year); return cal.getActualMaximum(DAY_OF_YEAR) > 365; } But if you are going to reinvent this wheel then: public static boolean isLeapYear(int year) { if (year % 4 != 0) { return false; } else if (year % 400 == 0) { return true; } else if (year % 100 == 0) { return false; } else { return true; } }
