[objectUitls] [stringUtils]

public class ObjectUtilsTest {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();
        Set<String> set = new HashSet<>();
        Map<String, String> map = new HashMap<>();
        Integer[] arr = {};
        Integer integer = null;
        String str1 = null;
        String str2 = "";
        String str3 = "s";
        System.out.println("list = " + ObjectUtils.isEmpty(list));
        System.out.println("set = " + ObjectUtils.isEmpty(set));
        System.out.println("map = " + ObjectUtils.isEmpty(map));
        System.out.println("arr = " + ObjectUtils.isEmpty(arr));
        System.out.println("integer = " + ObjectUtils.isEmpty(integer));
        System.out.println("str1 = " + ObjectUtils.isEmpty(str1));
        System.out.println("str2 = " + ObjectUtils.isEmpty(str2));
        System.out.println("str3 = " + ObjectUtils.isEmpty(str3));
    }
}

list = true
set = true
map = true
arr = true
integer = true
str1 = true
str2 = true
str3 = false

请问这种情况下，stringutils.isblank 的意义在哪里呢，，，

感觉处理，只判断 string=""时，需要用到 stringutils.isempty

stringutils.isblank 的存在意义，被 ObjectUtils.isEmpty 全部压住了
