Java about split split string, empty string cannot get the problem

1. Class T {
2. public static void Main (String args[]) {
3. String num[] = new STRING[11];
4. String sline = "101494|360103660318444|2008/06/17| Zhou Runying |1292.0|3085.76|2778.28|912.91|106.0| | |";
5. num = Sline.split ("\\|");
6. int row = 1;
7. for (String s:num) {
8. System.out.println (row+++ "=" +s);
9. }
10. }
11. }

There are three of the most | | |, running results
1=101494
2=360103660318444
3=2008/06/17
4= Zhou Runying
5=1292.0
6=3085.76
7=2778.28
8=912.91
9=106.0


To view the API, there is a

1. Public string[] Split (String regex, int limit);

The limit parameter controls the number of times the pattern is applied, thus affecting the length of the resulting array

if the limit n is greater than 0, then the pattern applies n>-1 times, the length of the array is not greater than N, and the last entry of the array will contain all inputs except the last match delimiter

if n non-positive, the number of times the pattern is applied is unlimited and the array can be any length

if n is zero, the number of times the pattern is applied is unlimited, and the array can be any length,and discards the trailing empty string

Modify the code to

1. Class T {
2. public static void Main (String args[]) {
3. String num[] = new STRING[11];
4. String sline = "101494|360103660318444|2008/06/17| Zhou Runying |1292.0|3085.76|2778.28|912.91|106.0| | |";
5. num = Sline.split ("\\|",-1); Use 1 as a parameter here
6. int row = 1;
7. for (String s:num) {
8. System.out.println (row+++ "=" +s);
9. }
10. }
11. }

Run the result as
1=101494
2=360103660318444
3=2008/06/17
4= Zhou Runying
5=1292.0
6=3085.76
7=2778.28
8=912.91
9=106.0
10=
11=
12=


Results are normal.
