I want to tokenize a String to key value pairs. But key has characters like underscore, comma, space etc. The key value pair is separated by = character

Example:

key=value start_time="2013-03-01 03:20:40" Key withspace=space1 two withspace=space2 key=value key-key key=value key_underscore=500058 key=value - value key= value_value

Desired output is

Key=value
start_time="2013-03-01 03:20:40"
Key withspace=space1
two withspace=space2
key-key key=value
key_underscore=500058
key=value - value
key= value_value

And this helps me to populate the value in a map and put it in a table.

Can i use any existing methods like StringTokenizer, Patter, String.split() etc. Or should i write my own String parser to get this type of output.

Just want to check some best methods to acheive this

Answer 1

String.split() takes a regex. If you can put in a regex to match your set of keys, you can use it

Answer 2

Key with spaces will not work, at least with the given rules. key=value - value key= value_value is ambiguos. The last key-value pair can be extracted as key = value_value or value key= value_value.
