Question

What is JDI?

Hint:

JDI is crucial for interacting with JVM and performing runtime debugging.

Answer 1

Step 1: Definition of JDI.
The Java Debug Interface (JDI) is part of the Java Platform Debugger Architecture (JPDA). It provides the necessary functionality for debugging Java applications, allowing developers to control the execution flow of a Java program, inspect variables, set breakpoints, and step through code during runtime.

Step 2: How JDI Works.
JDI interacts with the Java Virtual Machine (JVM) to access the runtime data of a Java application. It allows debuggers to interact with JVMs that are running Java programs, making it possible to perform operations such as halting program execution, checking variable values, and more.

Step 3: JDI's Role in Debugging.
JDI provides the interface for developers to programmatically debug their Java applications, which is essential for finding and fixing bugs in a timely manner.

Final Answer: \[ \boxed{\text{Java Debug Interface}} \]
