java中参数传递给方法,总是按值调用call by value。 在方法中,如果参数是对象,那操作的是对象的引用的拷贝。 如果参数是值,操作的是值的拷贝。 public class TestExtends { public static void main(String[]args){ A a =new A("bob"); A b = new A("lucy"); a.swap(a,b); System.out.println(...

A procedure executes when it is invoked, or called, by another procedure (or the operating system). The callee may return a value to its caller, in which case the procedure is termed a function. This interface between procedures lets programmers develop and test parts of a program in ...

java-callgraph2项目原本fork自https://github.com/gousiosg/java-callgraph。 后来进行了优化和增强,差别已比较大,不容易合并回原始项目中,且仅提供通过静态分析获取Java方法调用关系的功能,因此创建了该项目。 当前项目提供了插件功能,可用于为Java代码自动生成UML时序图,可参考https://github.com/Adrninistrator/...
