如何使用 Stream API 从对象列表中获取 object 的值

Question

From the below code require to get values based on type from List,

List<Type> types= Arrays.asList(new Type("type1","Values1"),new Type("type2","Values2"));

List<AnotherType> anotherTypes = new ArrayList<>();

for (Type type:types){
    AnotherType  anotherType = new AnotherType();
    
    anotherType.settype1Value(?);
    anotherType.settype2Value(?);

    anotherTypes.add(anotherType);
}

easy way to find values in the?.

I am not sure I understand you question. Next time you ask a question on StackOverflow try to provide the classes you are using and try to explain what exatly are you trying to achieve.

Having said that, to transform one object into another, using streams, you can use map() . Something like that:

List<AnotherType> anotherType = types
    .stream()
    .map(t -> new AnotherType(t.getTypeValue1(), t.getTypeValue2()))
    .collectors(Collectors.toList());
