 <dependency>
     <groupId>com.google.code.google-collections</groupId>
      <artifactId>google-collect</artifactId>

 </dependency>

用法：

 public static void main(String[] args) {
    
    
        List<String> list1 = null;
        List<String> list = Optional.ofNullable(list1).orElse( Lists.newArrayList()).stream().collect(Collectors.toList());
        Out.out(list);
    }
