First, we will introduce three methods for generating and running Java programs -----Java-generated jar packages are generally executed in three ways:1. Run j2se Binnary directly. The jar package can also be opened with WinRAR, causing a conflict. You can set the file association. In this case, the jar package and the. exe file are no different. In addition, the platform type is not lost.2. write scripts. It is. BAT in windows and. Sh in Linux or UNIX

Php frontend and backend separation technology when writing PHP programs, some code is used to process some transactions, such as database operations and mathematical operations, some other code is only the result of transaction processing, for example, some PHP code that uses echo statements to display results in HTML format on a Web browser and the HTML code that directly embeds the PHP program. First, we should clearly distinguish the two types of

When writing a PHP program, some code is used to process some transactions, such as database operations and mathematical operations. Other code is only displayed as the result of transaction processing, for example, some PHP code that uses echo statements to display results in HTML format on a Web browser and the HTML code that directly embeds the PHP program. First, we should clearly distinguish the two types of code, the former is called the background program, and the latter is called the fro

Use GDB to debug programs and gdb to debug programs GDB (GNU Debuger) is a powerful Debugger in Linux. GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.Compile To use GDB for debugging, you must add the
