重置动态对象的值的最佳方法是什么

// 使用对象字面量创建对象
let obj = { key1: value1, key2: value2 };

// 重置对象的值
obj.key1 = newValue1;
obj.key2 = newValue2;

// 定义一个类
public class MyClass {
    private int key1;
    private String key2;

    // 构造函数
    public MyClass(int key1, String key2) {
        this.key1 = key1;
        this.key2 = key2;
    }

    // setter方法
    public void setKey1(int key1) {
        this.key1 = key1;
    }

    public void setKey2(String key2) {
        this.key2 = key2;
    }
}

// 创建对象并重置值
MyClass obj = new MyClass(initialValue1, initialValue2);
obj.setKey1(newValue1);
obj.setKey2(newValue2);
