How to Convert String to Date in Java

by vigneshchennai74 Updated: Jan 24, 2023

Converting the string to a Date object allows you to validate that the date is in the correct format and valid. We can achieve this by following a simple algorithm. 


  • Firstly, we need to get the required string to be converted to a date. 
  • Next, we need to create an instant Timestamp object which should be empty. 
  • Timestamp: A timestamp denotes the number of seconds and nanoseconds. We can use the "Date" class of java. util package to get the current timestamp. 
  • Date: This java class includes some specific time with millisecond precision. 
  • Then, our string can be converted to date by using Instant.parse() method. 
  • Instant.parse(): This method converts the string into a date. The string is processed using DateTimeFormatter and must reflect a legitimate moment in UTC. 
  • DateTimeFormatter: This class is used to parse dates in various formats. 
  • If the string is converted to date successfully, print the date;, otherwise, throw DateTimeParseException. 
  • DateTimeParseException: This is an exception when an error occurs while parsing the string. It includes the string that is being parsed and the error. 


Here is an example on how to convert string to date in Java;
