用正则表达式很简单
String s="this is a test, powerful split";
String[] arr=s.split("[^a-zA-Z]+"); //6个单词的数组
for(int i=0;i<arr.length;i++)
System.out.println(arr[i]);
String s="this is a test, powerful split";
String[] arr=s.split("[^a-zA-Z]+"); //6个单词的数组
for(int i=0;i<arr.length;i++)
System.out.println(arr[i]);
