Implementation

Write a C program that documents JVM class loading concepts.

Requirements:

Print the three class loader names in hierarchical order
Show the delegation chain from Application up to Bootstrap
Describe what each loader is responsible for
Print a diagram or tree showing parent-child relationships
Output must contain the strings: classloader, bootstrap, delegation, and loading

Why This Matters

This delegation model is the real defense that stops malicious code from replacing java.lang.String, and it's also central to how servers like Tomcat isolate each deployed webapp with its own classloader so two apps can run different library versions side by side. Understanding it is essential background for reasoning about supply-chain classloading issues like Log4Shell (CVE-2021-44228), which exploited how JNDI lookups trigger dynamic class loading.
