如何在同一个Java类中访问另一个函数中的列表

public class MyClass {
    private List<String> myList = new ArrayList<>();

    public void addToList(String item) {
        myList.add(item);
    }

    public void printList() {
        for (String item : myList) {
            System.out.println(item);
        }
    }
}

public class MyClass {
    public void addToList(List<String> myList, String item) {
        myList.add(item);
    }

    public void printList(List<String> myList) {
        for (String item : myList) {
            System.out.println(item);
        }
    }
}

public class MyClass {
    public List<String> getList() {
        List<String> myList = new ArrayList<>();
        // 添加元素到列表中
        return myList;
    }

    public void printList(List<String> myList) {
        for (String item : myList) {
            System.out.println(item);
        }
    }
}
