Java Developer Kit FAQs
JDK includes the entire JRE, but it also provides additional development tools (compilers, debuggers, etc.) necessary for creating Java applications. JRE, on the other hand, is only used to run Java applications but lacks development tools.
JDK is available for various operating systems, including Windows, macOS, Linux, and Solaris. Each operating system has its specific JDK distribution.
Yes, JDK is free to download and use for development and production environments. However, be aware that Oracle JDK may have different licensing terms than OpenJDK distributions, so it's essential to understand the specific licensing conditions that apply to your use case.
Yes, you can use JDK to develop Java applications that run on various platforms, including Windows, macOS, Linux, and more, as long as the target platform has a compatible Java Runtime Environment (JRE) installed.
The "classpath" is an environment variable or parameter that specifies the locations where Java looks for classes and resources at runtime. It allows the Java compiler and the JVM to locate the required classes and libraries.
The setup process may vary depending on your operating system. Typically, you need to download the JDK package, install it on your machine, set the appropriate environment variables (like JAVA_HOME), and ensure your IDE or development tools reference the correct JDK version.
