BAT Batch Compilation execution Java

While there are powerful IDE tools such as Eclipse, it is sometimes unavoidable to use the command line to manually compile and execute Java programs,

Recently I have encountered such a problem, suddenly feel the compilation and execution of the name of the Java or class file, such a good trouble,

Happen to have just learned the next DOS system and batch processing, so you want to write a batch. bat, come on easy,

Although not complex, but the first batch processing or is stumped by some problems, but the Huang Tian, eventually wrote out:

Copy the following two sections of code, open Notepad, paste it, and save it as a file with the suffix: ". bat",

Then put these two. bat files anywhere on your computer, such as on your desktop (recommended on your desktop),

When you need to manually compile and execute Java later, drag the selected Java file onto the Myjavac.bat file,

This assumes that I save the first piece of code in order to Myjavac.bat file, the same myjava.bat,

The generated class file is automatically compiled into the directory where the Java file is located,

Then select the class file you want to execute and drag it onto the Myjava.bat file, and it will be executed in bulk,

Both of these applets support up to 9 Java or class files simultaneously compiled and executed,

Originally intended to be compiled and executed together with it, but think about it, or so separate better,

Here's the code:

Batch Compile Myjavac:

@echo offecho.for%%i in (% 1%2%3%4%5%6%7%8%9) do (%%~di && cd%%~dpi && javac%%i && if%e Rrorlevel%==0 echo%%~nxi compilation completed) Echo.pause

Batch execution Myjava:

@echo offecho.for%%i in (% 1%2%3%4%5%6%7%8%9) does (%%~di && CD%%~dpi && start call Java%%~ni) Ech O.pause
