![]() Just wanted to let you know that this story originally ran in our February issue, so if you like what you see, you should probably snag a hard copy ASAP. Here we discuss the introduction, How to check leap year in Java using various methods, and the Logics created.Hey, cutie. This is a guide to Leap Year Program in Java. It is important for other programs to have the logic before writing the code, as it becomes easy to code once the logic is done. But it is very important to keep the logic of century year in the code else, the output would be wrong in many cases. Many programmers get confused that leap year is the year that comes after every 4 years and forgets the logic of century year. The above description clearly explains what a leap year is, its logic and the code to implement the above logic. It depends on the choice of programmer what type of code he/she prefers (writing the core logic inside the main or in a separate function) for the newbies having less knowledge of the Java input classes, the programmer can perform the same task by directly inputting the year in the code itself and the main function or passing its value while calling its function. The programmer can also perform the above task creating a separate function of the leap year outside the main function and calling that function from the Java main function, keeping the logic the same. ![]() Since it is true, so the text mentioned “Given Year is a Leap Year” is displayed on the console. In the end, checking the value of the variable ‘isLeapYear’(which is a boolean variable holding true or false values).So the value of the boolean variable ‘isLeapYear’ becomes true. Since 2020 %100 != 0, we will move to the else part. Checking the even divisibility of 2020 by 100.Since 2020 %4 =0, we will move to the second step of the if statement. Checking the even divisibility of 2020 by 4.Checking the given year step by step according to the code written. Suppose we dry run the above code with an input value 2020. In the above code, we have implemented the above-mentioned logic with 3 steps using the if and else statements. Please find some of the snapshots of the outputs on executing the above program providing the different values of the years to check whether the year provided by the user is a leap year or not: Final checking the value of boolean variable ‘isLeapYear’ and displaying the final results on the console Checking the third condition of the year divisible by 100 and 400 both Checking the second condition of the century year (as we skip a leap year after every 100 years) Checking the first and foremost condition of leap year (" Please enter the year you want to test ") We have used the Scanner class to take the input from the user main method of java class from where the execution starts We have written the program of leap year in Java, taking the input from the user using the Scanner class. Step 5: Respective year entered by the user is not a leap year. Step 4: Respective year entered by the user is a leap year. Step 3: If the given year is evenly divisible by 400, go to step 4 else, go to step 5. Step 2: If the given year is evenly divisible by 100, go to step 3 else, go to step 4. Step 1: If the given year is evenly divisible by 4, go to step 2 else, go to step 5. Otherwise, logic will remain the same as mentioned above below given is the detailed algorithm implementing checking whether the given year is a leap year or not: How to use the if and else statements in Java.How to read input from the user in Java programming language using various input-output classes like Scanner, BufferedReader, Input Stream Reader, etc.To program the leap year in Java, one should have the knowledge of the following: How to check leap year in Java using various methods? Using the above mentioned 4 steps, the leap year program can be easily created in any programming language with the basic if and else statement usage. If the year is divisible by 100 but not by 400, it is not considered to be a leap year.If the year is divisible by 100, it should also be divisible by 400 then, it is considered a leap year.So, for a year to be a leap year, it should be divisible by 100. Since after every 100 years, we skip a leap year unless it is divisible by 400.In general, as the leap year occurs after every 4 years, so a leap year is the one that should be evenly divisible by 4.
