The Java Virtual Machine (JVM) is responsible for executing Java programs efficiently. Understanding JVM performance basics helps developers write faster, memory-efficient, and scalable Java applications.
Click Allocate to fill Heap Memory. When it gets full, run Garbage Collection.
The JVM converts bytecode into machine code using the JIT compiler. Memory is divided into heap (objects) and stack (method calls). Garbage collectors automatically clean unused objects to free memory.
// Simple program to observe JVM memory behavior
public class JVMBasics {
public static void main(String[] args) {
String data = "JVM Performance";
System.out.println(data);
}
}
JVM Performance
The JVM loads the class, allocates memory for objects, executes bytecode, and prints the output to the console.
