The preceding code snippet show how we can get the free memory in JVM before and after garbage collection using Java.

Here is the Java code written.

class Demo {
    public static void main(String s[]) throws Exception {
        Runtime rs = Runtime.getRuntime();
        System.out.println("Free memory in jvm before Garbage Collection = " + rs.freeMemory());
        rs.gc();
        System.out.println("Free memory in jvm after Garbage Collection = " + rs.freeMemory());
    }
}

Thank you, keep learning and sharing.
