Question

I want to split a string when following of the symbols encounter "+,-,*,/,=" I am using split function but this function can take only one argument.Moreover it is not working on "+". I am using following code:-

Stringname.split("Symbol");

Answer 1

String.split takes a regular expression as argument.

This means you can alternate whatever symbol or text abstraction in one parameter in order to split your String.

See documentation here.

Here's an example in your case:

String toSplit = "a+b-c*d/e=f";
String[] splitted = toSplit.split("[-+*/=]");
for (String split: splitted) {
    System.out.println(split);
}

Output:

a
b
c
d
e
f

Notes:

• Reserved characters for Patterns must be double-escaped with \\. Edit: Not needed here.
• The [] brackets in the pattern indicate a character class.
