while reading on reference type casting in Java's SE specification: Given a compile-time reference type S (source) and a compile-time reference type T (target), a casting conversion exists from S to T if no compile-time errors occur due to the following rules. I keep finding the following kind of condition: If S is a class type: If T is a class type, then either |S| <: |T| |S| <:
同时阅读Java SE规范中的引用类型转换： 给定编译时引用类型S（源）和编译时引用类型T（目标），如果由于以下规则而没有发生编译时错误，则从S到T存在转换转换。 我一直在寻找以下几种情况： 如果S是一个类的类型：如果T是一个类的类型，则是|S| <: |T| |S| <: |T| ，或|T| <: |S| |T| <: |S| 。 否则，会发生编译时错误。 此外，如果存在T的超类型X和S的超类型Y，使得X和Y都是可证明的不同参数化类型（§

我想查找当前使用Java代码连接到的本地网络中所有设备的IP地址。 有用的实用工具Advanced IP Scanner能够在我的子网192.168.178/24找到各种IP地址： 根据这个答案，我以如下方式构建我的代码： import java.io.IOException; import java.net.InetAddress; public class IPScanner { public static void checkHosts(String subnet) throws IOException { int timeout = 100; for (int i = 1; i <
我如何测试我的spring-boot应用程序的Scheduled / cron作业任务？ package com.myco.tasks; public class MyTask { @Scheduled(fixedRate=1000) public void work() { // task execution logic } } This is often hard. You may consider to load Spring context during the test and fake some bean from it to be able to verify scheduled invocation. I have such example in my Github repo.
我如何测试我的spring-boot应用程序的Scheduled / cron作业任务？ package com.myco.tasks; public class MyTask { @Scheduled(fixedRate=1000) public void work() { // task execution logic } } 这通常很难。 您可能会考虑在测试期间加载Spring上下文，并从中伪造一些bean来验证调度的调用。 我在Github回购中有这样的例子。 有一个简单的计划例子，用上述方法测试。 如果我们假设您的作业
Let's say I have a method m() that takes an array of Strings as an argument. Is there a way I can just declare this array in-line when I make the call? ie Instead of: String[] strs = {"blah", "hey", "yo"}; m(strs); Can I just replace this with one line, and avoid declaring a named variable that I'm never going to use? m(new String[]{"blah", "hey", "yo"}); Draemon is correct. You ca
比方说，我有一个方法m（），它将一个字符串数组作为参数。 有没有办法在我打电话时在线声明这个数组？ 即而不是： String[] strs = {"blah", "hey", "yo"}; m(strs); 我可以用一行替换它，并避免声明一个我永远不会使用的命名变量吗？ m(new String[]{"blah", "hey", "yo"}); 守护进程是正确的。 你也可以声明m作为可变参数： void m(String... strs) { // strs is seen as a normal String[] inside the method }
I have connected the oracle to my Java program, and it is working fine but it gives a problem on a primary key field, when I try to access it it throws an java.sql.SQLException : select user_id from users where users.user_name = '"+username+"' and `users.user_role = (select user_roles.role_id FROM user_roles where `user_roles.role_name = '"+role+"')" The query works, when ran in the sqlD
我已将oracle连接到我的Java程序，并且它工作正常，但它在主键字段上提供了一个问题，当我尝试访问它时，它将引发一个java.sql.SQLException ： select user_id from users where users.user_name = '"+username+"' and `users.user_role = (select user_roles.role_id FROM user_roles where `user_roles.role_name = '"+role+"')" 查询在sqlDeveloper中运行时起作用。 代码如下： Statement st = null; ResultSet r
How do you write an XML version 1.1 document in Java? Java only seems to support version 1.0.

How to mock methods with void return type? I implemented an Observer pattern but I can't mock it with Mockito because I don't know how. And I tried to find an example on the Internet, but didn't succeed. My class looks like public class World { List<Listener> listeners; void addListener(Listener item) { listeners.add(item); } void doAction(Actio
如何用void返回类型来模拟方法？ 我实现了观察者模式，但我不能用Mockito来嘲笑它，因为我不知道如何。 我试图在互联网上找到一个例子，但没有成功。 我的课堂看起来像 public class World { List<Listener> listeners; void addListener(Listener item) { listeners.add(item); } void doAction(Action goal,Object obj) { setState("i received"); goal.doAction(obj)
