How to check Java Version using Java Program

Last Updated: June 1, 2024 by Chaitanya Singh | Filed Under: java

In the previous guide, we learned how to check java version using command line. In this guide, we will write a Java program to check the java version. To do this, we can use the System class, which gives access to the system properties.

Program to check Java version

public class JavaVersionCheck {
public static void main(String[] args) {
// Get the Java version
String javaVersion = System.getProperty("java.version");
// Print the Java version
System.out.println("Java Version: " + javaVersion);
}
}

Output:

Java Version: 1.8.0_291

Here 1.8.0_291 indicates Java version 8, update 291.

Explanation

  • System.getProperty("java.version") retrieves the java version from the system. This checks which version of java is currently running on the system and returns the version details.
  • System.out.println prints the retrieved Java version.
