Dangling references and garbage, otherwise known as memory leaks, can occur in the same application and programming language. These symptoms are evidence of sloppy memory management by the programmer.
Dangling references and garbage collection cannot normally occur at the same time, as the garbage collector is not supposed to discard an item so long as there are still any references to it. Therefore, a reference can never "dangle" (i.e. refer to a no longer existing item).
garbage collection
Garbage collection prevents memory leaks. In Java, the Java Virtual Machine will garbage collect whenever there is memory that has no references.
GI/GO is a computer programming term for Garbage In/Garbage Out. It means that if you have incorrect data input, then your output will be incorrect
The Java Virtual Machine takes care of all the actual deletion for you. Once an object no longer has any references left, the garbage collector will come along and clear up that memory automatically.
Memory leaks do not occur in Java as the garbage collector clears the memory which has no references.
Garbage data in C, or in any programming language, occurs when a variable is read without having been initialized first.
garbage collection
A garbage truck. In computer programming, a process known as the garbage collector.
Regarding computer programming, GIGO means: garbage in, garbage out.
Yes, Java programming language has a Garbage collector for unused memory. and the best part about it is that it does it automatically. The Garbage Collector is built into the Java Virtual Machine, and will do automatic garbage collection for you. If you chose to compile your Java code down to native code (via a Java->native code compiler), then NO garbage collection is done for you.

When the object is no longer referenced anywhere else in your program, then the object becomes marked for garbage collection.

A Java object is ready to be garbage collected if there are no active references to the object. Let us say you declare an object of type ArrayList inside a for loop and process it. That object is local to the for loop and once the loop is executed there are no open references to the array list. Hence after the method is executed this object would be eligible to be garbage collected. The JVM garbage collector would search for such unused/unreferenced objects and clear them.
