【3】自定义元祖对象

public class TestFlagBean<K , V> {    private K value1;    private V value2;    public TestFlagBean(){}    public TestFlagBean(K value1, V value2) {        this.value1 = value1;        this.value2 = value2;    }    public K getValue1() {        return value1;    }    public V getValue2() {        return value2;    }    public void setValue1(K value1) {        this.v1 = value1;    }    public void setValue2(V value2) {        this.value2 = value2;    }}
