Question

I’ve got around 10 lines of data in a text file below containing the following

X-Value = -0.525108, Y-Value = 7.746691, Z-Value = 5.863008, Timestamp(milliseconds) = 23001
X-Value = -0.755030, Y-Value = 7.861651, Z-Value = 6.016289, Timestamp(milliseconds) = 23208

The code I have right now uses a BufferedReader reading every line of the file but what I really want to do is extract the X-Value, Y-Value, Z-Value and Timestamp(milliseconds) values from each line. Could this be done with using simple String methods such as substring or would this suit the use of regular expressions?

Answer 1

You can first split the strings by ,s, then split each part by =, then trim leading/trailing spaces as necessary.

You can use String.split() or java.util.StringTokenizer for this.
