First, change the JDK default encoding to UTF-8, guaranteed to start the JVM does not appear Chinese garbled problem1, at compile time, if we do not specify the encoding format of our Java source program with the-encoding parameter, then Javac.exe first obtains the encoding format that our operating system uses by default.The JDK first obtains the operating system's file.encoding parameter (it holds the operating system default encoding format, such a

Recently there is a need to start multiple child processes with a Java process to complete the concurrency task. Because the user must be given feedback on the task, the parent process is required to record the child process's life cycle.The Exec method returns a process object that invokes the Waitfor method of the object within the current process, and then the parent process blocks the method, which is r

Yesterday in the implementation of a Java program started executing C + + program, encountered some problems, first prepare to record it (for the benefit of people)The test function that is ready to be implemented is to start a C + + executable in a Java program, and then the Java program communicates with the C + + program (the

Execute shell using the exec function of php. many commands can be executed, but there is a problem with executing java programs. [Testshell. php] is as follows: {code...} the java file is also very simple. it is a test file that outputs helloworld and writes it to the file. In addition, I use php to directly execute this file... execFunction execution shell, Man

Before using Runtime.getruntime (). Exec calls an external program, and under Tomcat there is a phenomenon where the current thread waits. In order to solve this problem, using the new thread to receive output information from external programs, see the blog http://blog.csdn.net/accountwcx/article/details/46785437 for details.Later on the internet found open source Java call external Program class library A

Java executes the external program (Apache Commons Exec), apachecommons Use runtime.getruntime(cmd.exe c to call an external program. The current thread remains waiting in Tomcat.

For example, there is a Python script called test.py, which now wants to invoke this script in Java. Assuming that the test.py inside uses the extended package, making the embedded compiler such as Pythoninterpreter unusable, then only Java calls the console process, that is, Runtime.getruntime (). EXEC (), To run this Python script.Under Windows to run this prog
