What is the purpose of gc() in Java?

Comment

Java provides two methods System.gc() and Runtime.gc() to request

the JVM to run the garbage collection. By using these methods,

programmers can explicitly send request for Garbage Collection.

But JVM process can reject this request and wait for some time

before running the GC.

public class TestGarbage1{  
 public void finalize(){System.out.println("object is garbage collected");}  
 public static void main(String args[]){  
  TestGarbage1 s1=new TestGarbage1();  
  TestGarbage1 s2=new TestGarbage1();  
  s1=null;  
  s2=null;  
  System.gc();  
 }  
}
