问题 The ':javap' command in the scala 2.9.1 console need the tools.jar (from JDK6) in the 'classpath'. From cmd-line it could be done with '-cp' argument or CLASSPATH environment variable. How to do the same for scala console that invoked from SBT with the 'console' and 'console-quick' commands? 回答1: Long answer, that might help you elsewhere. If I want to know about something in SBT, I inspect it: > inspect console [info] Task: Unit [info] Description: [info] Starts the Scala interpreter with

问题 I was playing around with javap and some very simple code and that raised a - hopefully simple - question. here is the code first: public class Main { public static void main(String[] args) throws Exception { System.out.println(m1()); System.out.println(m2()); } private static String m1() { return new String("foobar"); } private static String m2() { String str = "foobar"; return new String(str); } } Now I compiled the code and looked at the output (omitting -verbose for now). $ javap -c Main

问题 As the title states, I'm trying to use javap with eclipse but have difficulties setting it up. I'm trying to set it up using external tools from the run menu but can't find the correct Arguments: string to make it work. Basically I need something that will dynamically execute the current file I have opened. 回答1: I use the following external tool configuration to achieve this: ${system_path:javap} is used to locate javap in the JDK used by the Eclipse. You can use an absolute path to javap

问题 I Wrote the following Code public class Reader1 { private int pageNumber; private class ReaderName1{ public int getPage(){ return pageNumber; } } static class ReaderFound{ } } When I used the Java Class File Disassembler javap on the compiled code I got 1. for Reader1.class class Reader1$ReaderName1 { final Reader1 this$0; private Reader1$ReaderName1(Reader1); public int getPage(); } 2. for Reader1$ReaderName1.class public class Reader1 { private int pageNumber; public Reader1(); static int

问题 Is there a tool similar to javap that could display methods and fields with their original (non-erased) types? I know that the type information is erased when source code is compiled. However, the compiler must know somehow, because it is able to determine if my calls to library methods match their signatures even if the library is already compiled into class files. So at least in theory, it should be possible to retrieve the type information. I searched further and I found this answer: Where
