Runtime runFinalization() in Java

runFinalization(): This method is available in the java.lang.Runtime class of Java.

Syntax:

void java.lang.Runtime.runFinalization()

This method runs the finalization methods of any objects pending finalization.

Calling this method suggests that the Java virtual machine expends effort toward running the finalized methods of objects that have been found to be discarded but whose finalize methods have not yet been run.

When control returns from the method call, the virtual machine has made the best effort to complete all outstanding finalizations.

Parameters: NA

Returns: NA

Exceptions: NA

Approach

Java

package com.Runtime;

public class RuntimerunFinalization {
    public static void main(String[] args) {

        Runtime runtime = Runtime.getRuntime();

        runtime.runFinalization();
        System.out.println("Successfully runs finalization");

    }
}

Output:

Successfully runs finalization
