So itCan find out what path the leak is associated with GC Roots and causes the garbage collector to not be automatically recycledof them. Having mastered the type information of the leaking object and the information of the GC Roots reference chain, it can be more accuratePosition the leak code.If there are no leaks, in other words, the objects in

It is well known that Java programs run on the Java Virtual Machine (JVM), so how is the memory allocated when the JVM is running? Each part of the program is stored in the memory of which part, and how to access, below, let me explain the Java Virtual Machine

introduced here: Run a constant-rate pool. It is primarily used to store the literal that is generated during compilation (literal simple comprehension is constant) and reference. In general, the memory allocations for constants can be determined during compilation, but not necessarily all, and some may be that the runtime can also put constants into a constant pool, such as a native method in the String Class intern () This complements a

same is true for deleting objects centrally. It causes a sudden emergence of a large number of garbage objects, the inevitable reduction of free space, thereby greatly increasing the next time to create a new object to force the main GC opportunity. 5, Java even if there is a GC will also occur memory leaks. An example is provided. 1. The use of static collect
