Verify Java

Using Control Panel

This is the easiest way to verify Java. Control Panel is one of the features of Windows OS. It helps users to manage system settings and configurations in one place. We can verify Java using the control panel by following the below-mentioned steps:

Step 1: Open the Control Panel on your system.

Step 2: Go to programs.

Step 3: Go to programs and features.

Step 4: Now check whether Java JDK is installed or not.

If it is there, then you can verify the Java version on your system.

Using Command Prompt

Using CLI(Command Line Interface), we can perform any task on our system. It is a type of user interface. It helps us to interact with the computer programs and features. To verify Java using CLI includes several steps:

Step 1: Open the CLI or Command Prompt on Windows.

Step 2: Enter the command java -version and then hit enter.

After hitting enter, you can verify the Java version on your system.

Verifying Java Using Search

You can simply search on your system whether Java is present or not. To verify Java using search includes several steps:

Step 1: Click on the Windows button.

Step 2: Enter Java in the search box and hit enter.

Step 3: Click on About Java.

You can verify the Java version on your system.

Using Java System Class

The System class is a built-in class in Java. It helps us to access the system information and resources. We can use it to get the current time, properties of the OS, and much information about our system. We can use the System class in Java to verify Java. We can use the getProperty() method of the System class with the argument java.version. Let us understand this with the help of an example:

Example:

public class JavaVerify {
public static void main(String[] args) {
String javaVerify = System.getProperty("java.version");
System.out.println("Your Java version is: " + javaVerify);
}
}

You can also try this code with Online Java Compiler

Run Code

Output 

Your Java version is: 17.0.4.1

You can use any IDE(Integrated Development Environment) to write this code to verify the Java version.

Frequently Asked Questions

How do I verify Java?

Java can be verified using three main types. The command prompt uses the command ‘java -version’ to check for the version of Java. By opening Control Panel and clicking on the Java icon, the version appears in the About section. And using the ‘getProperty()’ in the Java System class, we can also verify the Java version.

How to verify Java JDK?

The JDK can be verified through the following steps. Launch the Windows Start menu<

<Click on Programs<Find the program listing for Java<Click About Java to see the Java version. And for macOS users, the following steps will verify the JDK. Find the Java Control Panel on Mac<General tab<About section.

How to verify Java cmd?

To verify Java using the command prompt or CMD, first open and run the command prompt. Then check for the Java version and enter ‘java - version’ and run. Further, check for the Java Compiler by entering ‘javac - version’. By following these steps, the command displays the version of the Java version and compiler.

What is Java checker?

Java Checker is a framework making the software more effective and user-friendly. It checks and prevents errors in the Java program for users using compiler plug-ins. 

How to verify Java online?

Use online Java compilers such as JDoodle, CompileJava, or Repl.it, or visit the official Java website to check Java online. These platforms allow you to write or upload Java code, and they will build and run it while giving you feedback and results.

How do I verify the path of Java?

Type "java -version" into a command prompt or terminal window to see the location of Java on your system. The path to the Java executable and the installed Java version will be shown by this command.
