Determine leap year using Java?

Here is my requirements. Determine If a Year Is a Leap Year Algorithm:

• If the year can be evenly divided by 4, then it is a leap year
  • Except when the year can be evenly divided by 100, then it is not a leap year
• Except when the year can be evenly divided by 400, then it is a leap year
• Otherwise, it is not a leap year

I need to know if i did right?

private static boolean isLeapYear(int userInput){
    boolean leapYear= false;

    if (userInput % 4 == 0 ){
        leapYear = true;

        if (userInput % 4 == 0 && userInput % 100 ==0) {
            leapYear = false;

            if(userInput % 400 == 0){
                leapYear = true;
            }
        }
    }
    else {
        leapYear = false;
    }

    return leapYear;
}

userInput % 4 == 0 && userInput % 100 ==0 is equivalent to userInput % 400 == 0

and userInput % 4 == 0 then it is definitely Leap year so need not to check any other condition.
