like c#:
string[] Split(char[] separator, StringSplitOptions options)
is there an equivalent method in java?

This does what you want:
public static void main(String[] args) throws Exception
{
char[] arrOperators = { ',', '^', '*', '/', '+', '-', '&', '=', '<', '>', '=', '%', '(', ')', '{', '}', ';' };
String input = "foo^bar{hello}world"; // Expecting this to be split on the "special" chars
String regex = "(" + new String(arrOperators).replaceAll("(.)", "\\\\$1|").replaceAll("\\|$", ")"); // escape every char with \ and turn into "OR"
System.out.println(regex); // For interest only
String[] parts = input.split(regex);
System.out.println(Arrays.toString(parts));
}
Output (including the final regex for information/interest only):
(\,|\^|\*|\/|\+|\-|\&|\=|\<|\>|\=|\%|\(|\)|\{|\}|\;)
[foo, bar, hello, world]

Great. It works. Thanks. This can be accepted as the standard answer.
Take a look at public String[] split(String regex) and java.util.regex.

String[] split(String)
You can turn a char[] into a String with String(char[]).

char[] arrOperators = { ',', '^', '*', '/', '+', '-', '&', '=', '<', '>', '=', '%', '(', ')', '{', '}', ';' };

Illegal repetition near index 14
Possibly you want this. I'm not sure:
String text = "abcdefg";
System.out.println(Arrays.toString(text.split("d|f|b")));
Results in:
[a, c, e, g]

Another level up in functionality is Guava's Splitter:
Splitter splitOnStuff = Splitter.on(CharMatcher.anyOf("|,&"))
.omitEmptyStrings();
Iterable<String> values = splitOnStuff.split("value1&value2|value3,value4");

You have to use Regex, to achieve this. It will tell this on which basis you have to separate. Like there is OR "|" operator. If you use
String regex = "a|b|c";
String[] tokens = str.split(regex)
It will split on a,b & c basis.

And how are you using regex ??? Read up regex yourself first before misleading others . What you have above is a string vairble called regex you could call it dog or cat as well

@Shahzeb,
String.split(String) interprets its argument as a regex.guhai

I want to split a String using: char[] arrOperators = { ',', '^', '*', '/', '+', '-', '&', '=', '<', '>', '=', '%', '(', ')', '{', '}', ';' };
Goold ol' StringTokenizer will do it too:
public static void main(String[] args) {
String delim = ",^*/+-&=<>=%(){};";
String str = "foo^bar{hello}world";
StringTokenizer tok = new StringTokenizer(str, delim);
while (tok.hasMoreTokens()) {
System.out.println(tok.nextToken());
}
}
