The Java Development Kit (JDK) provides the runtime environment for Java bytecode to be executed. Here's how it works:
1. When a Java program is compiled, it is translated into Java bytecode, which is a set of instructions that can be understood by the Java Virtual Machine (JVM).
2. The JVM, which is part of the JDK, is responsible for interpreting and executing this bytecode on different platforms. It acts as a virtual machine that allows Java programs to run on any device or operating system that has a compatible JVM installed.
3. Therefore, when you install the JDK on your computer, it includes the JVM along with other tools needed for Java development, such as the compiler (javac) and other libraries.
4. In essence, the JDK not only allows you to compile your Java code into bytecode but also provides the necessary runtime environment (JVM) to run that bytecode and execute your Java programs.
By having the JDK installed, you ensure that your Java applications can be executed correctly across various systems that support Java.
