在java中将List<Rows>转换为List<long>

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        // 示例数据
        List<Rows> rowsList = new ArrayList<>();
        rowsList.add(new Rows(1));
        rowsList.add(new Rows(2));
        rowsList.add(new Rows(3));

        // 将List<Rows>转换为List<long>
        List<Long> longList = new ArrayList<>();
        for (Rows rows : rowsList) {
            longList.add(rows.getValue());
        }

        // 打印转换结果
        for (Long value : longList) {
            System.out.println(value);
        }
    }

    static class Rows {
        private long value;

        public Rows(long value) {
            this.value = value;
        }

        public long getValue() {
            return value;
        }
    }
}
