Which tool can be used to investigate Java memory issues?

• A. Memory leak detector
• B. HeapAnalyzer
• C. JVisualVM
• D. Java Memory Manager

Answer: (C)

C. JVisualVM is a powerful tool provided by the Java Development Kit (JDK) that facilitates the monitoring and troubleshooting of Java applications, specifically in the context of memory issues. It allows users to visualize memory consumption, analyze heap dumps, monitor garbage collection, and track memory usage over time. By doing so, it helps identify memory leaks, excessive memory usage, and other related performance issues within Java applications. JVisualVM provides insights into the overall health of Java applications and offers options to profile memory usage, which is essential for detecting and resolving memory problems effectively. It allows developers and system administrators to interactively examine Java processes running on the JVM, making it easier to pinpoint issues that may not be apparent through simple logs or other monitoring tools. Using JVisualVM can significantly enhance the ability to maintain the performance and reliability of Java applications by offering a comprehensive understanding of memory behavior at runtime.
