A stopwatch is a handy tool for measuring the execution time of methods, thus helping us track the elapsed time taken in parts of request processing. In this article, we’ll explore how to create a simple stopwatch in Java. 1. Implementing a Custom StopWatch in Java 8 SinceJava 8, we...
is available for Android applications as well. There are two techniques for creating threads in a Java program. One approach is to create a new class that is derived from the Thread class and to override its run() method. An alternative—and more commonly used—technique is to define a cla...
An object's age is a measure of how many times it has survived garbage collection. This is sometimes referred to as tenuring; see the -XX:+PrintTenuringDistribution option. Note that String objects that are promoted to an old heap region before this age has been reached are always ...

in order to examine the mastery of concurrent programming, they often examine the knowledge related to concurrent security and the knowledge of thread interaction. For example, how to implement a thread-safe singleton mode under concurrency, and how to complete the interactive execution of functions ...

Cyclomatic complexity (CC for short), also known as conditional complexity, is a measure of code complexity. Proposed by Thomas J. McCabe, Sr. in 1976, it is used to express the complexity of a program, and its symbol is VG or M. It can be used to measure the complexity of the deci...
Use theFlux Profiler packageto measure query performance and append performance metrics to your query output. The following Flux profilers are available: 使用Flux 探查器包测量查询性能并将性能指标追加到查询输出 一、如何使用InfluxDB的查询优化器:profiler ...
You may need to repeatedly call a method in order to reliably measure its average execution time. Minimize the possibility that CPU time will be allocated to anything other than the test while it is running by ensuring no other processes are runing during the test, and that the test remains...
