如何将映射转换为用户对象列表？

Question

我有一个具有以下结构的HashMap：

Map<Object, List<OtherObject>>

我想将其转换为：

List<FinalObject>

成为FinalObject：

public class FinalObject {
    private Object object;
    private List<OtherObject> otherObject;
}

Answer 1

假设您有一个类似的构造函数：

public FinalObject(Object obj, List<OtherObject> list) {
    this.object = obj;
    this.otherObject = list;
}

然后您可以做：

List<FinalObject> newList = map.entrySet()
                               .stream().map(e -> new FinalObject(e.getKey(), e.getValue()))
                               .collect(Collectors.toList());
