java - What does the provided regexp match? -
i've got regex i'm not sure {1,}
stands for. full regex next: ^.{1,}$
.
^.{1,}$
matches strings have atleast one of any(non-newline) character.
it same as: ^.+$
the general form of limiting quantifier is:
{min,max}
means minimum of min
repetitions not more max
repetitions.
you can drop max
part thereby specifying lower limit on number of repetitions , no bound on upper limit: {min,}
in case {1,}
means 1 or more repetitions.
