Question

is ist possible to tell String.split(“(“) function that it has to split only by the first found string “(“?

Example:

String test = "A*B(A+B)+A*(A+B)";
test.split("(") should result to ["A*B" ,"A+B)+A*(A+B)"]
test.split(")") should result to ["A*B(A+B" ,"+A*(A+B)"]

Answer 1

Yes, absolutely:

test.split("\\(", 2);

As the documentation for String.split(String,int) explains:

The limit parameter controls the number of times the
pattern is applied and therefore affects the length of the resulting
array. If the limit n is greater than zero then the pattern
will be applied at most n – 1 times, the array’s
length will be no greater than n, and the array’s last entry
will contain all input beyond the last matched delimiter.
