问题 I am trying to open *.docx files programmatically from Java on Mac OS X.

问题 I'm currently working on a project where a client receives shell/console commands from a server, and must execute them. How do I get Java to run these commands from within either a shell or a command prompt? I'm hoping to be able to disregard the platform type - and not have to specify shell or command prompt - but if I can't, then that's okay. I must be able to send a sequence of related commands, not just one command. This means that the shell/prompt cannot exit or close between commands.

问题 I have to write a Test case in JUnit for a Class lets call it C1 which internally calls Runtime.getRuntime.exit(somevalue) . The class C1 has a main method which accepts some arguments and the creates a CommandLine and then depending on the passed arguments does the specific tasks. Now all tasks after executing call a Runtime.getRuntime.exit(somevalue) . The somevalue defines whether the task was executed successfully (means somevalue is 0) or had errors (means somevalue is 1). In the JUnit

问题 I'm working on ionic 2. I've created a menu for my page and an array of contents for menu. menuItems: Array<{title: string, icon: string, method: any}> And added elements. this.menuItems = [ {title: "Edit Account", icon: "create", method: "editAcount()"}, {title: "Change Password", icon: "create", method: "changePassword()"}, {title: "LogOut", icon: "log-out", method: "logOut()"}, ]; And I'm calling methods at run-time. <ion-item *ngFor = "let item of menuItems" menuClose (click) = "item

问题 I want to create a full cross-plateform console in Java. The problem I have is when I use the cd command, the path is reset. For example, if I do cd bin , then cd ../ , I will execute the first one from the directory of my app and the second one exactly from the same directory. If I want to go to a specific folder and execute a program I have to do something like that: cd C:\mydir & cd bin & start.exe What I want to do is to split this cmd in different parts: cd C:\mydir then cd bin then

问题 I am trying to merge 2 programs I have made to one .jar file. One program is a .jar written in java and the second one is an .exe written in c++. I put both files to the new .jar, wrote this code but it didn't work. When this code was exported to .jar and executed neither of 2 files ran and I got error "no main manifest attribute, in merged.jar" in cmd. Though it worked perfectly when run in eclipse. public class main { public static void main(String[] args) { try { Runtime.getRuntime().exec(

问题 I have a little executable program in C that produce a lot of output to a file. When I call this program with Runtime, like this: Runtime r = Runtime.getRuntime(); Process p = null; p = r.exec("./my_program -in input.file -out output.file", null, new File(System.getProperty("java.io.tmpdir"))); When the program produce low output everything is ok, but when I call "*my_program*" with a large input it will produce a large quantity of output to the output.file, but in this case my program in
