In my Java program, I have a string like G C / F C / F C / F A / B / F / I
I am not much comfortable with Regex and would like to break the above string like below
G
C / F
C / F
C / F
A / B / F / I
Break it using some regex pattern like if character+space+character occurs, break the string.
Added from the comments
By character I meant [A-Z]. Tried this
(\s([a-zA-Z]\s)+)
but didn't work.
The following pattern can be used with find to extract the desired substrings.
[A-Z](?:\s/\s[A-Z])*
See this demo at regex101 or a Java demo at tio.run
There is not much to explain here. Just a repeated (?: non capturing group ) containing the slash part. If you want to match lower letters as well, simply add those to the character class: [A-Za-z]
This regex is pretty simple and seems to work:
let regex = /([A-Z])\s([A-Z])/g;
let str = 'G C / F C / F C / F A / B / F / I';
str = str.replace(regex, '$1\n$2');
console.log(str);
