[Introduction] String intern in Java 6,7,8 – String Pool This article will discuss how the String intern method is implemented in Java 6, and what this method does in Java 7 and Java 8 Adjustment. String Pool String Pool (Named String Normalization) This parameter is not of much help in Java 6 because you are still limited to the fixed PermGen memory size. The rest of the discussion will simply ignore the fact that in Java 6 you must set a larger -XX:StringTalbeSize value (compared to the default 1009) if you want to use String.intern() more often - otherwise this method will quickly reduce to 0 (pool size).

How to use code performance? Summarize code performance example usage

Introduction: Javascript is a very flexible language. We can write various styles of code as we like. Different styles of code will inevitably lead to execution efficiency. During the development process, I came into contact with many methods to improve code performance. Let me sort out the common and easy-to-avoid problems: Javascript's own execution efficiency, scope chain, closure, prototype inheritance, eval and other features in Javascript. , while providing various magical functions, it also brings various efficiency problems. If used carelessly, it will lead to low execution efficiency. 1. Global import we will use more or less in the coding process..

Java implementation "write once, run everywhere" is compiled into bytecode and run on a Java virtual machine (JVM). 1) Write Java code and compile it into bytecode. 2) Bytecode runs on any platform with JVM installed. 3) Use Java native interface (JNI) to handle platform-specific functions. Despite challenges such as JVM consistency and the use of platform-specific libraries, WORA greatly improves development efficiency and deployment flexibility.
