专家管理。对专家信息的增、删、改、查、导入、导出管理。专家信息一般包括姓名、专业、年龄、职称、所在单位，职务等。JAVA代码

好的，以下是一个简单的 Java 代码示例，实现了专家信息的增加、删除、修改、查询、导入和导出功能：

import java.util.ArrayList;
import java.util.List;

public class ExpertManagementSystem {
    private List<Expert> experts = new ArrayList<>();

    public void addExpert(Expert expert) {
        experts.add(expert);
    }

    public void deleteExpert(Expert expert) {
        experts.remove(expert);
    }

    public void updateExpert(Expert expert) {
        for (int i = 0; i < experts.size(); i++) {
            if (experts.get(i).getId() == expert.getId()) {
                experts.set(i, expert);
                break;
            }
        }
    }

    public List<Expert> findExpertByName(String name) {
        List<Expert> result = new ArrayList<>();
        for (Expert expert : experts) {
            if (expert.getName().equals(name)) {
                result.add(expert);
            }
        }
        return result;
    }

    public List<Expert> findExpertByTitle(String title) {
        List<Expert> result = new ArrayList<>();
        for (Expert expert : experts) {
            if (expert.getTitle().equals(title)) {
                result.add(expert);
            }
        }
        return result;
    }

    // 导入专家信息
    public void importExperts(List<Expert> experts) {
        this.experts.addAll(experts);
    }

    // 导出专家信息
    public List<Expert> exportExperts() {
        List<Expert> result = new ArrayList<>();
        for (Expert expert : experts) {
            result.add(expert.clone());
        }
        return result;
    }
}

public class Expert implements Cloneable {
    private static int idCounter = 0;
    private int id;
    private String name;
    private String field;
    private int age;
    private String title;
    private String organization;
    private String position;

    public Expert(String name, String field, int age, String title, String organization, String position) {
        this.id = idCounter++;
        this.name = name;
        this.field = field;
        this.age = age;
        this.title = title;
        this.organization = organization;
        this.position = position;
    }

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getField() {
        return field;
    }

    public void setField(String field) {
        this.field = field;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getOrganization() {
        return organization;
    }

    public void setOrganization(String organization) {
        this.organization = organization;
    }

    public String getPosition() {
        return position;
    }

    public void setPosition(String position) {
        this.position = position;
    }

    @Override
    public Expert clone() {
        try {
            return (Expert) super.clone();
        } catch (CloneNotSupportedException e) {
            return null;
        }
    }
}

这是一个简单的专家管理系统的实现，其中 `Expert` 类表示一个专家，`ExpertManagementSystem` 类表示专家管理系统，提供增加、删除、修改、查询、导入和导出专家信息的功能。
