How to Check Java SDK Version
In the ever-evolving world of software development, it is crucial for developers to be aware of the Java SDK version they are using. Knowing the Java SDK version helps in ensuring compatibility with various libraries, frameworks, and tools. It also aids in identifying potential issues and bugs that may arise due to version discrepancies. In this article, we will discuss several methods to check the Java SDK version on different operating systems.
Using the Command Line
One of the simplest ways to check the Java SDK version is by using the command line. Here’s how you can do it on various operating systems:
– On Windows:
1. Open the Command Prompt.
2. Type `java -version` and press Enter.
3. The output will display the Java SDK version you are currently using.
– On macOS and Linux:
1. Open the Terminal.
2. Type `java -version` and press Enter.
3. The output will display the Java SDK version you are currently using.
Using the Java Home Directory
Another method to check the Java SDK version is by examining the Java Home directory. This directory contains information about the Java SDK version you are using. Here’s how you can find the Java Home directory and check the version:
– On Windows:
1. Open the Command Prompt.
2. Type `echo %JAVA_HOME%` and press Enter.
3. The output will display the Java Home directory path.
4. Navigate to the `bin` folder within the Java Home directory.
5. Open the `java` file using a text editor.
6. Look for the line `version=”` in the file. The value following this line is the Java SDK version.
– On macOS and Linux:
1. Open the Terminal.
2. Type `echo $JAVA_HOME` and press Enter.
3. The output will display the Java Home directory path.
4. Navigate to the `bin` folder within the Java Home directory.
5. Open the `java` file using a text editor.
6. Look for the line `version=”` in the file. The value following this line is the Java SDK version.
Using Java SDK Manager
If you are using the Oracle JDK, you can also check the Java SDK version using the Java SDK Manager. Here’s how to do it:
1. Open the Java SDK Manager.
2. Click on the “Java” tab.
3. The list of installed Java SDKs will be displayed. The version of the currently selected SDK is displayed at the top of the list.
By following these methods, you can easily check the Java SDK version on your system. Being aware of the Java SDK version is essential for efficient and bug-free development.
