![]() Java provides several methods that can be used to operate on the date object which make operation on date and time simpler and reliable. Date objects can be created using the Date or LocalDate class in Java. If the given date is, then the Date pattern for this will be yyyy-MM-dd.ĭate object is a built-in datatype that is supported by Java. ![]() As the letter used to represent a date is d, a month is M, and year is y. If the given date is, then the Date pattern for this will be dd/MM/yyyy.The below table illustrates the letter that is used to represent various time and date entities like a year, month, etc in a Date format string. You can refer to this link for more details. The below table illustrates some of the common date and time pattern strings that are used in, which is an inbuilt class in Java. There are four main ways we can do that, we shall look at each of them with an example.īefore you jump into the actual conversion methods, let us take a look at the common Date and Time patterns/notations that are used in Java. This article illustrates how to convert string to date in Java. Then the in-built after() and before() methods can be used to find out if the current date is after or before a given date with the added advantage that they support parsing of many input string date formats. They parse the given input string and convert them into date objects. You can follow the above steps to solve the problem or you can make use of inbuilt java Date classes and methods that does all the above steps for you. Now compare the years, months, and dates individually with appropriate logic.Convert the current year, month, and date to integers.Get the current date string, and extract the year, month, and date.Convert the input year, month, and date to integers.The input is given as a string, so you’d be writing the program to extract the year, month, and date parsing the given input string.Introduction to Java Convert String to DateĬonsider the example where you are given the date in string format and are asked to write a program that returns if the date is in the past, present, or future. To specify the date-time pattern used in the input string, we can use DateTimeFormatter and SimpleDateFormat classes. We can convert String to Date in Java using the parse() method of LocalDate, Instant and SimpleDateFormat classes.
