public class SplitterTest {

    public static void main(String args[]){

     //1、拆分字符串为List集合
        String str="小小,妈妈,爸爸,爷爷,奶奶";
        Splitter splitter =Splitter.on(",");
        List<String> list=splitter.splitToList(str);
        System.out.println(list);
        //输出：[小小, 妈妈, 爸爸, 爷爷, 奶奶]

     //2、忽略空字符
        String str1="a,b,c,d,,f,g";
        //omitEmptyStrings()代表去除空字符串
        List<String> list1=Splitter.on(",").omitEmptyStrings().splitToList(str1);
        System.out.println(list1);
        //输出：[a, b, c, d, f, g]

     //3、忽略空字符且去除字符串前后空格
        String str2="a,b,c,d,,f,  g  ";
        List<String> list2=Splitter.on(",").omitEmptyStrings().trimResults().splitToList(str2);
        System.out.println(list2);
        //输出：[a, b, c, d, f, g]
    }
