如何在IntelliJ IDEA中向项目添加外部库,以便在构建工件时它仍然可以访问库中的类?
我从Project Structure创建了一个新的Jar工件,然后将外部JAR添加到Libraries,然后在Modules List中检查它,最后将它添加到Artifact的Output中.这些都不起作用.当我构建并尝试运行我的应用程序时,它会抛出一个错误:
Exception in thread "main" java.lang.NoClassDefFoundError: <path of the class trying to use>
我错过了什么,或者我完全错了?
在C++中,以下哪个解决方案从0到99计数更加健壮和可靠,并将每个迭代存储在数十个和一个位置的变量中?如何改进任何一种方法,使其尽可能快速和非资源密集?
typedef int (*IntFunction) (int* _SegmentList);
int display1SegmentPinNums[] = {...pin numbers...};
int display2SegmentPinNums[] = {...other pin numbers...};
// Then I have some functions that display a number to 7-segment displays. They each return an integer 1 and have a parameter of (int* _SegmentList), as per the type definition above
// An array of all the functions
IntFunction displayFunctions[10] = {display_0, display_1, display_2, display_3, display_4, display_5, display_6, display_7, display_8, display_9};
// Solution 1
for (int tens = 0; tens < 10; …
