**Objective**: Given a Year, write a java program to find whether year is leap year or not.

**Leap Year**: a year, usually occurring once every four years, that has 366 days including February 29 as an intercalary day, called Leap Year.

**Example**:

Year: 2004, 2008, 2012 are Leap years. Year: 1993, 2001, 2003 are not leap years.

**Approach: **

**Pseudo code:**

if(yearis not divisible by 4)then(its not a leap year)else if(yearis not divisible by 100)then(its a leap year)else if(yearis not divisible by 400)then(its not a leap year)else(it is a leap year)

public class LeapYear { | |

static void isLeapYear(int year){ | |

if(year<=0){ | |

System.out.println("Invalid year entry"); | |

return; | |

} | |

//check for leap year | |

boolean isLeap; | |

if(year%4==0){ | |

if(year%100==0){ | |

if(year%400==0){ | |

isLeap = true; | |

}else{ | |

isLeap = false; | |

} | |

}else{ | |

isLeap = true; | |

} | |

}else{ | |

isLeap = false; | |

} | |

if(isLeap) | |

System.out.println("Given year " + year + " is leap year"); | |

else | |

System.out.println("Given year " + year + " is not leap year, its a common year"); | |

} | |

public static void main(String[] args) { | |

isLeapYear(1992); | |

isLeapYear(2000); | |

isLeapYear(2001); | |

isLeapYear(2002); | |

isLeapYear(2004); | |

} | |

} |

**Output**:

Given year 1992 is leap year Given year 2000 is leap year Given year 2001 is not leap year, its a common year Given year 2002 is not leap year, its a common year Given year 2004 is leap year
