Check whitespaces and isempty

I am looking for a if statement to check if the input String is empty or is only made up of whitespace and if not continue with the next input. Below is my code so far which gives an error when I input a whitespace.

    name = name.trim().substring(0,1).toUpperCase() + name.substring(1).toLowerCase();
    if(name != null && !name.isEmpty() && name.contains(" ")) {
        System.out.println("One");
    } else {
        System.out.println("Two");
    }
