bytecode

问题 I need to know if with the following code and with javassist I can manipulate the code to replace the logical operator ">" with "<". Here is the class whose bytecode I want to manipulate: public class TryClass { public void foo(){ int a =0; if(a>5){ System.out.println("I love apples"); } else{ System.out.println("I hate apples"); } } } After the manipulation the execution of the class should print: "I love apples" instead of: "I hate apples" 回答1: there is no < or > at the byte code level per

问题 I would like to analyse .class files and get information about which class uses which other class. jdeps is a command line tool which allows you to display some information in the console, but I would like to avoid calling an external tool and scraping the command line output. 回答1: All dependencies are recorded at a central place of a class file, the constant pool. So to efficiently process all dependencies, you need a library allowing to process the constant pool without looking at the rest

问题 Is there a way to move a my Python program to other computer without the need of re installing all the required module? Maybe by compilation? 回答1: I think you're looking for PyInstaller. By definition, PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, Solaris and AIX. PyInstaller as of this writing, doesn't support Python 3. There is however this page on freezing your code or shipping: Solution | Windows | Linux |

问题 So I have some malfuctioning code to debug where SOMEthing throws an NPE and I'd like to step through some generated methods in order to try and find out why. Except stepping blindly is not really useful. Thread-4[1] list Source file not found: Foo.java Thread-4[1] locals Local variable information not available. Compile with -g to generate variable information The code was generated, so of course there is no .java file available for JDB. And since I don't compile it with javac, there's no
