Parsing strings using `split`

Terminology	General template for using `split`
parsing token delimiter	`String line = string_to_parse; String delims = "[delimiters]+"; String[] tokens = line.split(delims);` (use `+` to treat consecutive delims as one; omit it to treat consecutive delims separately)

Example 1

String input = "23x239 u12x120:x23=5203 28340:23\n238";
String delims = "[:x]+";
String[] tokens = input.split(delims);

for (int i = 0; i < tokens.length; i++)
	System.out.println(i + ") " + tokens[i]);

What is printed out?

Example 2

Suppose a weather observation station has collected weather information for this year in a text file data.txt in which each line has the format

day time temperature where

day represents the day of the year and is between 1 and 366
time represents the time of day the temperature reading was taken (hh:mm:ss, in 24-hour format)
temperature is between -127.8 ^oF and 135.9 ^oF

For example, the first few lines of the file might look like:

1   04:45:53  -13.3 
23  14:01:17    7.5
63  11:32:28   23.8
126 13:45:37   71.5

Complete the fileVerifier method that takes the name of a file as input and returns true only if every line in the file has the appropriate format (including appropriate ranges for the values). For each line with an invalid format, a descriptive error message should be printed.

public static boolean fileVerifier(String fileName) {
