如何抑制未经检查的课堂警告

Question

how to I pass HashMap<String, String>.class in Gson builder for supperss "unchecked warning"?

HashMap<String, String> manifest = 
    Gson().fromJson(stringBuilder.toString(), HashMap.class);

Answer 1

用@SuppressWarnings("unchecked")标记您的方法

Answer 2

Please add @SuppressWarnings("unchecked") above your Hashmap reference. This will only ignore the next statement to it instead of whole method.

@SuppressWarnings("unchecked") 

HashMap<String, String> manifest = 
        Gson().fromJson(stringBuilder.toString(), HashMap.class);
