问题 Hey, I have the following two lines of code: result[i] = temp[i] + temp[i + 1] + " " + temp[i + 2]; i += 2; I am wondering if this line of code would do the same: result[i] = temp[i] + temp[i++] + " " + temp[i++]; Can I be sure, that EVERY VM would process the line from the left to the right? Thanks, Tobi 回答1: From Java language specification: The Java programming language guarantees that the operands of operators appear to be evaluated in a specific evaluation order, namely, from left to

问题 Not sure if this is Parallels related, but I'm running Visual Studio 2013, and one day I my documents started closing after debugging a .NET project. The expected behavior is that all the files that are open would stay open, but now they all close. Even after closing the program that's debugging, if I try to open a document to view the code, a new tab does not open because VS thinks the file is still "open." One fix is to go to Window > Close All Documents which closes the files that were

问题 Launching a VM using a marketplace image in Azure is pretty straight forward. here is the relevant piece of code. def create_vm(network_client, compute_client): vm_parameters = { 'storage_profile': { 'image_reference': { 'publisher': 'MicrosoftWindowsServer', 'offer': 'WindowsServer', 'sku': '2012-R2-Datacenter', 'version': 'latest' } }, vm = compute_client.virtual_machines.create_or_update( GROUP_NAME, VM_NAME, vm_parameters ) (Clearly there is more in the actual code, this is the part that

问题 I am self leaning Java rookie and I doth (as in Shakespeare 'Doth')received the following error message back when trying to start the Android 1.6 VM( The reason I am using Android 1.6 and not later versions is that it takes less time to load on my slow P.C!) from Eclipse: Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/ref/FinalReference I have successfully started Android 1.6 VM from the AVD manager so the VM software appears to be O.K. and the source

问题 I am looking to upgrade the machine type on my Google Cloud. The handful of solutions I've found all mentioned the follow: 1) Delete old instance while preserving disk. 2) Create new instance using the disk from the old instance. None of the solutions provide any details though. How do you accomplish the 2 steps above in detail? I created a test instance (Bitnami LAMP stack), then tried deleting it, but it didn't give me any option to "preserve disk" when deleting, or "select another disk"

问题 I've researched the questions already on stackoverflow that suggest upgrading to the most recent version of Virtual Box; one question at the time suggested upgrading to V4.3.14. Well, I'm on V 4.3.20. I've reinstalled about 5 times, and ensured the BIOS was set to virtualization. I continue to get the error message below. Failed to open a session for the virtual machine Hortonworks Sandbox with HDP 2.2. The virtual machine 'Hortonworks Sandbox with HDP 2.2' has terminated unexpectedly during

问题 I have installed the Docker for Windows in my windows 10 machine. When I'm trying to "switch to linux container" from "windows container", I'm getting an error.

问题 So I want to start using yeoman (Gruntjs/requirejs/bower), but I was wondering if this could be done from inside your vm or would it be better for my workflow to have it installed on my host machine (OSX)? As far as I know you need to have a couple dependancies like node.js. Is this a subjective thing or is there a guideline? 回答1: As @matt-cooper said, it's a subjective thing. Personally, I run it on my host because that's where git and my IDE live and I consider Yeoman etc to be development

问题 I need to add -Djava.security.policy=myPolicyFile so that my RMI jar would work. Or is there some other way to make that run? 回答1: If you're wanting to add the -D when someone launches your jar using java -jar , that's not possible because it's not possible to specify JVM options inside the jar: Can I set Java max heap size for running from a jar file? That said, if you're in control of the process, you could use java.security.Policy.setPolicy to manage the policy object yourself. 回答2: You
