because garbage collection suspends other work (may use multithreading or time slices, and it doesn't feel that way)2 speeds up the replication speed. Because the heap is internally flush to the remote, it is copied to direct memory (not heap memory) and then sent, while the outer heap memory is equivalent to omitting the work. Heap External
to reclaim memory. As soon as the maximum heap memory set by-XMX is reached, if no more memory can be allocated to the new object, the JVM throws the java.lang.OutOfMemoryError and the program goes down. Before throwing the OutOfMemoryError, the JVM tries to use the garbage collector to free up enough space, but when
In C programming, memory that is often required to operate can be divided into the following categories:
Stacking area (Stack): Automatically allocated and disposed by the compiler, parameter values for stored functions, local variables, temporary variables, and so on, all of which are obtained automatically by the compiler.
Heap Area (heap): Generally by the programmer allocation and release, the base programmer does not release, the pro
is a memory leak in Java, we must first understand how Java manages memory. The memory management of Java is the allocation and release of objects. In Java, the allocation of
the JVM.
When we create objects, they are stored in the Java heap memory.
To facilitate garbage collection, the Java heap space is divided into three zones, called New Generation, old Generation or tenured Generation, and perm space.
You can resize the Java heap space by using the Jvm's command-line Opt

OverviewThere is a high wall between Java and C + + that is surrounded by dynamic memory allocations and garbage collection techniques, and people outside the walls want to go in, but the people inside the wall want to come out.For developers engaged in C, C + + program development, in the field of memory management, they are the highest power of the emperor is t
dynamically view the memory usage. After a project is launched, a memory overflow error occurs two days after the system is started. This situation is generally caused by slow memory leakage in the code, which cannot be solved by the above three steps. Therefore, you need to use the memory check tool.
There are many

Java memory allocation and recovery mechanisms are summarized as follows: generational allocation and generational collection.

Java divides memory into two types, called stack memory, which is called heap memory.some basic types of variables and object reference variables defined in the function are allocated in the stack memory of the function. When a variable is defined in a block of code, Java al

Recycle () method, we should call recycle () to free the memory before it is set to NULL for the Bitmap object when not in use. Because the memory space of the Bitmap object is loaded, part of it is Java, part C (because the bottom of the Bitmap allocation is called through JNI). And this recyle () is for the C part o
for garbage collection, which means we don't need to call the function to free up memory, but in the JVM, the memory can still overflow. As more and more server programs use Java technology, such as Jsp,servlet, EJB, and so on, server programs often run for long periods of time. In addition, in many embedded systems,
