main

问题 Here is my code: public class Main { public static void main(String[] args) { Main p = new Main(); p.start(args); } @Autowired private MyBean myBean; private void start(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("META-INF/config.xml"); System.out.println("my beans method: " + myBean.getStr()); } } @Service public class MyBean { public String getStr() { return "string"; } } <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3

问题 I tried searching around but didn't seem to find an answer to my problem, so I'm sorry if I missed something and it actually has been answered before. So basically I have main.py and another file called check.py (both in same directory) In my main.py I have: from check import checkfunction I have a small function inside main.py that I MUST call inside check.py, but I can't seem to get this import working on my check.py: from main import mainfunction How can I get the mainfunction to work

问题 Up to this point I've been able to correctly view the output of my C codes by using the debugging command in Visual C++. However, when the script relies on parameters in the main function (eg/ argc , argv ), the debugger seems to ignore both parameters and treat them as though they are uninitialized. For instance, in the following code, the output is always printf("Usage: find pattern\n"); . #include <stdio.h> #include <string.h> #define MAXLINE 1000 int getline(char *line, int max); /* find:

问题 I came across this snippet of code: section .text global main ;must be declared for linker (gcc) and then there is a function called main after this line: main: ;tell linker entry point but i don't seem to understand what global main means, and the comment doesn't seem to help much... i am using this site as a reference to Assembly language programming. i can analyse that main refers to the function main, but i don't understand the use of the global keyword... thank you in advance... 回答1:

问题 hi i have an c function int main(int argc, char *argv[]) and my wrapper.c has this function JNIEXPORT jint JNICALL Java_package_Class_lameMain(JNIEnv *env, jclass class, jint argc, jcharArray argv) { return main(argc, argv); } and in java i've defined it like this private native int lameMain(int argc, char[] argv); but i think i'm doing something wrong with the argv-argument... it's not an char-array, but a array of char-pointers. can anyone help? when i run it my app crashes with 03-20 23:26

问题 What does the C int main() function return when the program hits a run-time exception (e.g. segmentation fault)? When searching for an answer I hit many discussions/posts about what main() should return, like this one. 回答1: It (the main function) doesn't return if the program crashes. If a program crashes, then the operating system would have killed the program, so the program isn't running anymore and that includes the main function. A program that doesn't run can't return anything on its

问题 This question already has answers here : Python 3- Assign grade (2 answers) Closed 3 years ago . • Define a function to prompt the user to enter valid scores until they enter a sentinel value -999. Have this function both create and return a list of these scores. Do not store -999 in the list! • Have main( ) then pass this the list to a second function which traverses the list of scores printing them along with their appropriate grade. I am having trouble with the getGrade function, it gives

问题 I've written two python scripts script1.py and script2.py. I want to run script1.py from script2.py and get the content of the variables of script1 created during the execution of script1. Script1 has several functions in which the variables are created including in the main. Thank you for all your answers. I've examined your answers and it doesn't seem to work. Here are the guilty scripts I'm talking about : script1.py def main(argv): """Main of script 1 Due to the internal structure of the

问题 Is it bad practice to, in the class which contains the main method, declare all members of that class as static? If so, why? Is it better to, in the main method, create a new instance of the enclosing class, and run the program from the constructor so to speak? EDIT: (clarification) I know the concept about static and singletons and generally when to use it. But this question regards specifically the main-class of a program. @Andrew Tobilko (who apparently removed his answer..) seems to have

问题 I looked up other similar questions and couldn't find a solution, so here I am. I am a complete beginner in Java and android programming, even though I have a quite good knowledge of C and basic knowledge of C++ and Python, as well as a few more specific programs like Mathematica and ROOT. I tried making an extremely simple android app: a number displayed and two buttons which raise or decrease the number, but I get tons of errors. If you kindly have time to help me, I feel really discouraged
