s we can cal Gc explisitly but it Reduces the performance.

Yes we can call the Garbage collector explicitly by using
method Collect().

Ex. Create object for the Garbage collector.

    GarbageCollector Gc = new GarbageCollector();
    Gc.Collect();

not required to create object
we can call directly
System.GC.Collect();

But forcefully calling Garbage collector reduces the
performance. As when CLR runs Garbage collector
automatically it checks all the objects which are not used
for a long time and remove them. But if we use
System.GC.Collect(), it will shift the particular object to
cache. When CLR founds no object which is made to be free
then it will check the cache memory from there it will
remove that very object. So, how it is reducing the performance.

we can call the garbage collection explicitly but performing a garbage collection is totally dependent on the JVM. So calling System.gc() does not necessarily performing the garbage collection.
