Garbage collector can be run forcibly using “System.gc()” or “Runtime.gc()”

In Java, you cannot explicitly force the garbage collector to run. The garbage collector in Java is managed by the Java Virtual Machine (JVM), and it runs automatically to reclaim memory when it determines that objects are no longer reachable and eligible for garbage collection.

However, you can suggest to the JVM that it’s a good time to run the garbage collector by calling System.gc() or Runtime.getRuntime().gc(). Keep in mind that these methods are not guaranteed to force an immediate garbage collection. The decision to run the garbage collector is ultimately up to the JVM, and it may choose to ignore the request.

Here’s an example:

java

public class GarbageCollectorExample {

public static void main(String[] args) {

// Your code here

// Suggesting garbage collection
System.gc(); // or Runtime.getRuntime().gc()
}
}

It’s generally considered good practice to let the JVM manage garbage collection automatically, as it is designed to optimize the process based on the application’s needs. Explicitly trying to control the garbage collector may not result in improved performance and can be counterproductive in some cases.
