HashMaps中类的多个对象

Question

我在创建B类对象时遇到问题，所有对象都应该是分开的。但是当我对其中一个对象进行更改时，所有对象都会进行相同的更改。应如何实践？这是一个示例代码：

CLASS A：

public class A {

    private static HashMap<String, B> map = new HashMap<String, B>();
        public void newObject (String name) {
            if (map.containsKey(name)) {

        } else {
            Person person = new Person (name);

            map.put(name, person);

        }
    }

    //This method gets called several times, to create several objects

    //But it everytime i create a new object, all the old/existing objects change too.


}

CLASS Person：

public class Person {
    private static String name;

    public Person (String name) {
        this.name = name;
    }

}

Answer 1

将name中的Person从静态变为私有（将其作为成员变量）。
