按字符串排序鏈接列表

Question

我正在嘗試對鏈接列表進行排序，並不斷獲取“找不到適合sort（LinkedList，>）的合適方法。我在做什么錯？

public Contributor(String firstName, String lastName, String city,
            String country, String phone, double contribution, int id) {
        // CONSTRUCTOR WITH ALL ATTRIBUTES PASSED
        this.firstName = firstName;
        this.lastName = lastName;
        this.country = country;
        this.phone = phone;
        this.contribution = contribution;
        this.id = id;
    }

public static LinkedList<Contributor> contributorList = new LinkedList<>();



Collections.sort(contributorList, new Comparator<String>() {
            @Override
            public int compare(String o1, String o2) {
                return Collator.getInstance().compare(o1, o2);
            }
        });

Answer 1

通過比較貢獻者對象，使用比較器進行排序。

Collections.sort(contributorList, new Comparator<Contributor>() {
    @Override
    public int compare(Contributor o1, Contributor o2) {
       return Collator.getInstance().compare(o1.lastname, o2.lastname);
    }
});
