按可比接口排序ArrayList

Question

实际上，我想对对象数组列表进行排序。我正在为此目的使用可比接口。它是完全有效的，但问题是，当我排序的时候，是给这两个问题。

所有名字中有第一个字母大写的都在上面，所有名字中有第一个字母小写的都在下面。

所有排序的大写字母单词都在一起，然后所有的小写字母单词都在一起。

   public class Myshares implements Comparable<Myshares> {

        int id, parent;
        String name, path, type, shared_with, shared_or_not, upload_request;

        public int getParent() {
            return parent;
        }

        public void setParent(int parent) {
            this.parent = parent;
        }

        public String getUpload_request() {
            return upload_request;
        }

        public void setUpload_request(String upload_request) {
            this.upload_request = upload_request;
        }

        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getPath() {
            return path;
        }

        public void setPath(String path) {
            this.path = path;
        }

        public String getType() {
            return type;
        }

        public void setType(String type) {
            this.type = type;
        }

        public String getShared_with() {
            return shared_with;
        }

        public void setShared_with(String shared_with) {
            this.shared_with = shared_with;
        }

        public String getShared_or_not() {
            return shared_or_not;
        }

        public void setShared_or_not(String shared_or_not) {
            this.shared_or_not = shared_or_not;
        }

        @Override
        public int compareTo(Myshares another) {

            return this.name.compareTo(another.getName());
        }

    }

如果您希望使用不区分大小写的排序，我建议更改compareto()方法，改为使用string的comparetoignorecase()方法，即：

public int compareTo(Myshares another) {
    return this.name.compareToIgnoreCase(another.getName());
}
