If it's date, space, then entry then you can find the index of the first space using indexOf and split the String using substring. Another alternative is using a Regular Expression, but those are used far too often (they're an expensive tool you shouldn't reach for quite so early).

just parse the line to what u need . Also one huge advice. Do not post stuff like that, it will chase people away and not take u serious at all

for example suppose u have the text (x : 123, y - 45) and u want to extract the numbers 123 and 45, then regex could do that for u easily with the pattern \(x[ :-]+(\\d+), y[ :-]+(\\d+)\)

#

or alternatively just the pattern \\d+ being applied multiple times

#

in java this is done using the classes Pattern and Matcher

i mean, in ur specific case it wouldnt be that difficult

#

for a text like 20/10/2022 life suck, regex could split it into the two parts using: (\\d+/\\d+/\\d+) (.+)

#

but yeah, for this specific string, a simple split on the first space would suffice as well

#

int index = text.indexOf(' ') tells u where the first space is at

#

and then u can just text.substring(0, index) and text.substring(index + 1) or sth like that
