Using Regex for spaces

[brave anchor]

Hello, I currently use !hasnext() to try and ensure that the input word doesn't have any characters other than letters, which works fine
however I am not sure how to make it so that regex also detects whether or not any spaces are in the input

You can use \s (any whitespace) or similar for spaces

or just normal spaces to only match that

I assume you are using the Scanner#hasNext(Pattern) method?

Note that by default, hasNext/next only checks one token

so it doesn't go over multiple spaces

you can use useDelimiter to change that behavior

If you want to check it per line, you can set line breaks as delimiters

alr ty

lemme check if it works rq

[brave anchor]

yeah

[brave anchor]

yeah thats fine

how come this doesn't work

[mortal pollen]

As I said, hasNext stops at \s by default

[brave anchor]

wdym

im not following

[brave anchor]

by this you mean that it only check to see if there is at least one space right?

the input string has multiples spaces

but "No!" still doesnt run

[mortal pollen]

if you have an input like Hello World, hasNext/next only sees the Hello

unless you have a custom delimiter

[brave anchor]

ohhh

wait 1 second

let me test smth

eesh

[mortal pollen]

hasNext/next only sees one token but you can configure what is used to split tokens

[brave anchor]

how would i make it only take that first word then?

like if hello word was input

how would i make it just take hello

[mortal pollen]

hasNext()/next() literally does that by default without any regex

[brave anchor]

oh

1 sec again

right

i see what u mean

well that solves my issue entirely ngl

nextLine --> read entire line
next --> read one token (word)

[brave anchor]

alr thanks man

[mortal pollen]

but you cannot just use nextLine after next

[winter pelican]

If Scanner#nextLine reads an empty line after calling a different Scanner#next method, take a look at this StackOverflow post.
