Run-Time Polymorphism: Runtime polymorphism occurs when an object is associated with functionality during runtime. Method overriding can be used to provide runtime polymorphism. The Java virtual machine selects the method to invoke during runtime, not at compile time. It’s also known as dyna...
provided 跟compile相似,但是表明了dependency 由JDK或者容器提供,例如Servlet AP和一些Java EE APIs。这个scope 只能作用在编译和测试时,同时没有传递性。??? runtime 表示dependency不作用在编译时,但会作用在运行和测试时,如JDBC驱动,适用运行和测试阶段。 test 表示dependency作用在测试时,不作用在运行时。 只在测...
The types of errors encountered when a software developer develops a Java application can be split into two broad categories: compile time errors and runtime errors. As the name implies, compile time errors occur when the code is built, but the program fails to compile. In contrast,Java runt...
那就看是语法错误还是逻辑错误了,语法错误就是编译时出错,逻辑错误就是运行时出错,逻辑错误比如说是算法错误,比如判断偶数写成了%2==1这样的 runtime /logic error运行时，才发生错误compile-time error编译就发生了错误
关键报错是:Incompatible because this component declares a component for use during compile-time, compatible with Java 17 and the consumer needed a component for use during runtime, compatible with Java 11,翻译过来就是:组件使用 Java 17 编译的,但是运行时使用的 Java 11 环境。
java maven scope compile,provide,system,test,runtime,在一个maven项目中,如果存在编译需要而发布不需要的jar包,可以用scope标签,值设为provided。如下:<dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version
Maven dependency scope is used to specify the visibility of a dependency. It provides six scopes i.e. compile, provided, runtime, test, system, and import.
