我不明白这段代码的输出:

public class StringDemo{              
    public static void main(String args[]) {
        String blank = "";                    
        String comma = ",";                   
        System.out.println("Output1: "+blank.split(",").length);  
        System.out.println("Output2: "+comma.split(",").length);  
    }
}

得到以下输出:

Output1: 1 
Output2: 0
