    Java Program To Perform GC

    Uploaded by

    vinchooo
    This Java program prints the free memory before and after calling garbage collection to demonstrate how it works. It uses the Runtime class's getRuntime() and freeMemory() methods to get the current runtime object and check available memory. The gc() method is then called to perform garbage collection and freeMemory() prints the amount, showing more available memory afterwards.

    This program performs garbage collection.
    Free memory in java virtual machine is
    printed and then garbage collection is done
    using gc method of RunTime class,
    freeMemory method returns amount of free
    memory in jvm, getRunTime method is
    used to get reference of current RunTime
    object.
    Java programming source code
    import java.util.*;

    class GarbageCollection
    {
    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());
    }
    }

    Output of program:

    Obviously the amount of available after


    garbage collection will be different on your
    computer. Numbers are not important,
    what is important is that amount of memory
    available is more than before. You can use
    this code in your program or projects which
    uses large amount of memory or where
    frequently new objects are created but are
    required for a short span of time.
