示例数据类
后续所有算子演示的数据，均来自此类来提供公共数据。
import org.apache.flink.api.java.tuple.Tuple3;
import java.util.Arrays;
import java.util.List;
/**
* @Description 公共示例数据
*/
public class DataSource {
/**
* 示例数据集合
* Tuple3 是一个固定3个属性变量的实体类，分别用f0,f1,f2表示三个构造传参与变量
* @return
*/
public static List<Tuple3<String,String,Integer>> getTuple3ToList(){
//Tuple3<f0,f1,f2> = Tuple3<姓名，性别（man男，girl女），年龄>
return Arrays.asList(
new Tuple3<>("张三", "man", 20),
new Tuple3<>("李四", "girl", 24),
new Tuple3<>("王五", "man", 29),
new Tuple3<>("刘六", "girl", 32),
new Tuple3<>("伍七", "girl", 18),
new Tuple3<>("吴八", "man", 30)
);
