GC stands for garbage collector - this is the mechanism which cleans up unused object references. The GC is why memory management in Java is almost non-existent.

When does Garbage collection occur in java?
No one can force garbage collector to free memory, A java object is subjected to garbage collection when it can not be reached by the program in which it is being used. Programmer can request for garbage collection by System.gc() but JVM doesn't guarantee that is will start immediatelyActually, the specific method for GC and how it will be run is dependent on the JVM implementation being used.For instance, Sun (now Oracle)'s Hotspot JVM has several different GC designs, one of which (the RealTime engine) can be immediately triggered via a System.gc() call. Each type of GC will have different triggers and thresholds as to when it will be run, which allows the user to pick the GC option that they think will be least disruptive and most effective for their particular application.You must read the JVM documentation for your particular VM to see what available GC options there are, how each GC method works, and what the various thresholds are.
What are the differences between gc methods of System and Runtime Classes in Java?
There is actually no difference between System.gc() and Runtime.gc(). They both essentially invoke the JVM's Garbage Collection operation. The System.gc() is a static method so it's a little bit more convenient to use. The call System.gc() is effectively equivalent to the call: Runtime.getRuntime().gc()
Memorymically and and not reclaming it when it is no longer it is needed in java there is no such problem as there is as garbage collector what is it?
I guess you want to talk about the garbage collector feature that Java has. The garbage collector is an automated program that the Java virtual machine would run once in a while. This program would clean up unused memory to ensure that there is enough memory available for the programs. you can invoke the garbage collector by calling the system.gc() method but this does not guarantee an invocation of the garbage collector. the JVM may or may not call the GC when we invoke it...

What are the different java technologies?
There are several types of Java technology. Some examples of Java software are Java ME, Java EE, Java SE, and Java Card. Java made the JAVA development kit for those that develop in Java. There is also Java Virtual machine and some class libraries. Java is also famous for its languages like Clojure, Beanshell, Groovy, Gosu, Rhino, Kotlin, JRuby, Scala, and Jython.
Can GarbageCollector in java be forced to immediately recover unused memory?
No. Even if we manually invoke the GC it would not recover the unused memory immediately.
What is difference between java and c sharp garbage collector?
The one for Java is not invoke/control by the application. The one for .net (C# is just one of the languages) is invokable (may be called) but still no control over when the gc should run, how long to run, etc.
