如何动态合并Java对象

import org.apache.commons.beanutils.BeanUtils;

public class MergeObjectsDemo {
    public static void main(String[] args) throws Exception {
        // 创建两个Java对象
        SourceObject source = new SourceObject();
        source.setName("Source");
        source.setAge(20);

        TargetObject target = new TargetObject();
        target.setName("Target");
        target.setGender("Male");

        // 合并两个Java对象
        BeanUtils.copyProperties(target, source);

        // 输出合并后的对象
        System.out.println("Merged object: " + target);
    }
}

class SourceObject {
    private String name;
    private int age;

    // Getter and setter methods
}

class TargetObject {
    private String name;
    private String gender;

    // Getter and setter methods
}
