How to split a comma-delimited string into an array of empty strings1个
String abc = "a,b,c,d,";
String[] arr = abc.split(",");
System.out.println(arr.length);
String abc = "a,";
abc += "\n";
String[] arr = abc.split(",");
System.out.println(arr.length);
为什么会这样？有谁可以给我一个更好的解决方案？

String abc = "a,",-1); System.out.println(arr.length);

从上面链接的Javadoc：
If n is non-positive then the pattern will be applied as many times as possible and the array can have any length. If n is zero then the pattern will be applied as many times as possible,the array can have any length,and trailing empty strings will be discarded.
