Other, such as a run-time exception of 0 and other checks, requires the programmer to examine carefully, each function must be checked (unless it can be determined that

Some developers often reflect the following situation: I have a statement or a job that ran for half an hour yesterday. How can I run for two hours today? Is there a problem with the database? The abnormal running time of database statements is actually a complicated situation. Because the data is constantly changing, a good statement may be executed tomorrow. This scenario cannot be completely retraced within the estimated time. Even if there is backup data at the time, there is no way to

1. Run-time data areaThe Java Virtual machine divides the memory it manages into several different data regions during the execution of a Java program. These areas have their own uses, as well as the time of creation and destruction: Some regions exist with the start of a virtual machine process Some regions are built and destroyed depending on the start and end of the user thread Accordin

A lot of times this kind of anomaly how to produce all silly confused, if can deliberately write to let JVM memory overflow code, sometimes it seems not easy.

Program Counter: The JVM considers this count as the number of rows that the current thread executes for a byte code, and selects the action statement to be executed based on the value of the counter. This is a thread-private, non-shareable, and cannot be accurately executed by the curr
