How to match the patterns in java with assert J for below string
To build on the answer of stevecross, note that the suggested expression is pretty lenient. For example, it will match this:
String xyz =" ID: VERSION: "You can be more strict in your matching if needed. Say, if you need to ensure non-blank words, use + instead of * like this:
assertThat(xyz).matches("[A-Za-z]+ +ID: [0-9]+ +VERSION: [0-9]+");And if you need to have exactly three spaces between the key-value pairs, then add {3} to a class of characters including only space ([ ]), like this:
assertThat(xyz).matches("[A-Za-z]*[ ]{3}ID: [0-9]*[ ]{3}VERSION: [0-9]*");I find online regex evaluators helpful. See for example this one: https://regex101.com/
