把一个LIst转换成另一个List的两种方法

Method 1:

myFinalList = new ArrayList<>();
myListToParse.stream()
        .filter(elt -> elt != null)
        .forEach(elt -> myFinalList.add(doSomething(elt)));

Method 2:

myFinalList = myListToParse.stream()
        .filter(elt -> elt != null)
        .map(elt -> doSomething(elt))
        .collect(Collectors.toList());
