1,程序计数器(Program Counter Register):程序计数器是一个比较小的内存区域,用于指示当前线程所执行的字节码执行到了第几行,可以理解为是当前线程的行号指示器。 字节码解释器在工作时,会通过改变这个计数器的值来取下一条语句指令。 每个程序计数器只用来记录一个线程的行号,所以它是线程私有(一个线程就有一个程...
You may often need a counter to understand the frequency of something (e.g., words) from a database or text file. A counter can be easily implemented by using a HashMap in Java. This article compares different approaches to implement a counter. Finally, an efficient one will be concluded...

Once we have that working we'll add in some other paths that will result in different data coming back from the "server" (aka the Java program you are writing and will have running on the machine). You can do the next steps either in this repo or in your new project that you've ...
The easiest way to instrument non-C/C++ programs is to write a C library and call it from your non-C/C++ program. For example, in Java, it is possible to use the Java Native Interface (JNI) to call C/C++ functions. There may also be tools in other environments that enable access ...
