Checking if Java is installed on your system is a crucial step before running Java-based applications or developing Java programs. Java is a widely-used programming language for various applications, including web development, mobile apps, and enterprise software.
To verify if Java is installed, you can use different methods depending on your operating system. On Windows, you can open the Command Prompt (cmd) and type “java -version”. On macOS and Linux, you can use the Terminal application and run the same command. If Java is installed, the command will display the installed Java version and other relevant information.
