当我试图解决某个数据集时,我得到了这个错误(环境模式设置为full_assert)
14:14:40.603 [main] INFO o.o.core.impl.solver.DefaultSolver - Solving started: time spent (39), best score (0hard/0medium/-18soft), environment mode (FULL_ASSERT), random (JDK with seed 0).

我必须为这个问题编写多项式时间算法,如果左边的数字与右边的数字不匹配,则应该说接受或拒绝。您也可以对数字进行分组,示例如下
X&Y.&N=和where X, Y, and N can be any integer
Case 1: 4 & 6 & 10 = 14 , accepts
So case 1 accepts because first number and the third number together sum up to 14.
Case 2: 4 & 6 & 10 = 8 rejects
Case 3: 4 &
使用List<Optional<PersoonFast>> (其中PersoonFast是一个合适的类)作为@ValueRangeProvider,我得到以下异常:
Exception in thread "main" java.lang.IllegalArgumentException: The entityClass (class nl.smartinstall.titania.solver.Bezetting) has a PlanningVariable annotated property (persoon) that refers to a
我正在尝试实现一个具有JDBC postgresql db源连接的流应用程序。作为开始,我尝试了一个基本查询,但是由于强制转换异常,我无法执行它。
以下是例外情况

我使用swing JFrame作为我的应用程序的MainFrame。我有一个按钮,应该创建一个新窗口。但是它会在初始化时崩溃,我不知道原因。
public class Dialog {
private Stage window;
public void display() {
window = new Stage(); //This is line 45. This is place where it crash
window.setMinWidth(350);
window.setMinHeight(500);
window.initModalit
我已经编写了显示上周用户计数的MongoDB查询,基于个人资料收集的lastActive字段,lastActive字段是日期字符串。谁能帮我写相应的Spring Boot java代码使用SimpleDateFormat类或LocalDate类。请 var today = new Date();
var lastWeekStart = new Date(today.getFullYear(), today.getMonth(), today.getDate() - 7);
var lastWeekEnd = new Date(today.getFullYear(), today.getMon
我试图在我的解决方案中实现自定义克隆,我遵循了文档中的说明,并遇到了一个例外形式的路障:The entity was never added to this ScoreDirector. Maybe that specific instance is not in the return values of the PlanningSolution's entity members。我知道这不是真的,因为在定制克隆之前,没有抛出这个异常。
我的planningClone方法的设置如下:
@Override
public Solution planningClone() {
Sol
下面的代码会导致连接重置错误。导致连接重置的确切原因是什么?是因为我试图忽略SSL证书验证的方式吗?
String serviceUri = "https://service.providers.com/applications";
String reqJson = "request json string";
//this is to ignore SSL validation.
SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new T
我开始学习java,这就是我的问题:如何写到三角形的右边?
import java.util.Scanner;
public class Triangle {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("please enter your siz triangle :");
int lines = scanner.nextInt();
