What are Environment Variables in Java?
In Java, Environment variables are values that are stored outside of your program but can be accessed by Java code. Typically, environment variables are used to configure various features of your program or to store sensitive information like as API keys or database connection strings.
Environment variables are named values that the Java Virtual Machine (JVM) and Java applications use to configure their behavior. Any Java application that requires them can access them. They are normally specified by the operating system or the user.
