public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("请输入您的症状（多个症状之间用逗号分隔）："); String symptomsString = scanner.nextLine(); List<String> symptoms = Arrays.asList(symptomsString.split(",")); System.out.println("请输入您的流行病学史："); String history = scanner.nextLine(); System.out.println(DiagnosisChecker.diagnose(symptoms, history)); } }基于决策表方法实现测试，用Java代码编写

好的，这是一个基于决策表方法实现测试的Java代码：

import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入您的症状（多个症状之间用逗号分隔）：");
        String symptomsString = scanner.nextLine();
        List<String> symptoms = Arrays.asList(symptomsString.split(","));
        System.out.println("请输入您的流行病学史：");
        String history = scanner.nextLine();
        System.out.println(DiagnosisChecker.diagnose(symptoms, history));
    }
}

class DiagnosisChecker {
    static String diagnose(List<String> symptoms, String history) {
        Map<List<String>, String> decisionTable = new HashMap<>();
        decisionTable.put(Arrays.asList("发热", "咳嗽", "喉咙疼", "流感病史"), "流感");
        decisionTable.put(Arrays.asList("发热", "咳嗽", "喉咙疼"), "感冒");
        decisionTable.put(Arrays.asList("咳嗽", "气喘", "胸痛"), "支气管炎");
        decisionTable.put(Arrays.asList("呼吸困难", "胸痛", "咳嗽", "痰液带血"), "肺炎");
        decisionTable.put(Arrays.asList("腹泻", "腹痛", "恶心", "呕吐"), "肠胃炎");
        decisionTable.put(Arrays.asList("腹泻", "腹痛", "恶心"), "肠炎");
        decisionTable.put(Arrays.asList("头痛", "恶心", "呕吐"), "偏头痛");
        
        for (List<String> condition : decisionTable.keySet()) {
            if (symptoms.containsAll(condition) && history.contains("疫区")) {
                return "您可能感染了" + decisionTable.get(condition) + "，请尽快前往医院就诊！";
            }
        }
        return "根据您的症状和流行病学史，暂时无法确定您的疾病，请咨询医生。";
    }
}

这个程序会要求用户输入症状和流行病学史，然后根据预先定义的决策表来诊断可能的疾病。如果输入的症状和流行病学史符合某个条件，就会返回相应的疾病名称，否则返回无法确定。注意，这个程序只是一个简单的示例，实际的决策表可能会更加复杂。
