The Serial collector is the most basic and oldest collector in the Java Virtual Machine. It was the only choice for collecting new generations of J
The current commercial virtual machine garbage collection uses the "generational collection" algorithm, that is, according to the different life cycle of the object, divided into several pieces of memory, generally for the Cenozoic and the old era, different generations according to its characteristics of the use of the most appropriate

program executes, unless the space is reassigned or reclaimed by another method. This shows that it is impossible to completely eradicate the generation of memory leaks. Don't forget, though, that Java's garbage collector frees programmers from the heavy work of manually reclaiming memory space. Imagine a programmer using C or C + + to write a 100,000-line statement of code, then he will be fully aware of the Jav

The working principle of the Java garbage collection mechanism.
Java's heap is a run-time data area in which instances (objects) of the class allocate space. The Java Virtual machine (JVM) heap stores all objects that are established by the running application, which are established through directives such as new, New

The Java heap is a runtime data zone, and the instance (object) of the class allocates space from it. The Java Virtual Machine (JVM) Heap stores all objects created by running applications. These objects are created through commands such as new, newarray, anewarray, and multianewarray, however, they do not need program code to be explicitly released. In general, the heap is responsible for

program cannot recycle its memory space and the system does not have any memory space to allocate when the program runs, the program will crash. Generally, the memory space that we can't recycle After allocating is called "Memory leakage (memory leaks )".
The potential danger of the above program design is not allowed in a rigorous and secure language such as Java. However, the Java language neither limit
