Converting a String to a LocalDate in Java is a common operation when you are dealing with date inputs from users. Java provides the LocalDate class in the java.time package for representing a date without time information. LocalDate class is part of the java.time package introduced in Java 8.

String to a LocalDate Conversion in Java

LocalDate.parse() method of the java.time.LocalDate class to convert a String representation of a date into a LocalDate object. The parse() method will take the date string and a DateTimeFormatter (yyyy-MM-dd) as parameters.

Syntax to Define an Input Format

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");

Syntax to Convert String Date into LocalDate

LocalDate localDate = LocalDate.parse(dateString, formatter);

Program to Convert String to LocalDate in Java

An example demonstrates how to convert String data into LocalDate:

Converted LocalDate: 2024-01-20

Explanation of the above Program:

• First, We have imported the necessary classes: LocalDate, DateTimeFormatter.
• Then inside the try-catch block, We have defined a String variable dateString that value is in yyyy-MM-dd format.
• We have used DateTimeFormatter.ofPattern() method to define format of our input dateString.
• By using a LocalDate.parse() method, we are converting date string into a LocalDate.
• After converting, we are printing the output.
• If an exception occurs during parsing, we catch it and print an error message.
