Understanding Java memory management, including the stack and heap, garbage collection, and how to monitor and optimize memory usage, is crucial for developing efficient Java applications.
Source Code
Runtime runtime = Runtime.getRuntime();
long usedMemoryBefore = runtime.totalMemory() - runtime.freeMemory();
// Execute your application logic here
long usedMemoryAfter = runtime.totalMemory() - runtime.freeMemory();
System.out.println("Memory used: " + (usedMemoryAfter - usedMemoryBefore));
Regularly monitor your Java application’s memory usage, especially in long-running applications, to avoid OutOfMemoryError and other memory-related issues.
