Calculate memory usage at runtime


If you’re wondering how to calculate memory usage, this tip is what you need

// Get the Java runtime
Runtime runtime = Runtime.getRuntime();
// Run the garbage collector
runtime.gc();
// Calculate the used memory
long memoryUsed = runtime.totalMemory() - runtime.freeMemory();
