拆分字符串列表并将单词添加到新列表中

优雅的方法如下：

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

public class Main {
    public static void main(String[] argv) throws Exception {
        List<String> newList = List.of("Amitabh Bachchan", "James Bond", "Kishore Kumar", "Arvind Kumar Avinash");
        List<String> words = newList.stream().flatMap(s -> Arrays.stream(s.split(" "))).collect(Collectors.toList());
        System.out.println(words);
    }
}

输出

[Amitabh, Bachchan, James, Bond, Kishore, Kumar, Arvind, Kumar, Avinash]
