How I can split the sentences with respect to the delimiters in the string and count the frequency of words ?
String delimiters = "\t,;.?!-:@[](){}_*/";

Try with
split("\\t|,|;|\\.|\\?|!|-|:|@|\\[|\\]|\\(|\\)|\\{|\\}|_|\\*|/");
Also
The split method takes as argument a regular expression so, to use multiple delimiters, you need to input a regular expression separated by the OR regex operator or using a character class (only if the delimiters are single characters).
Using the OR operator:
String delimiters = "\\t|,|;|\\.|\\?|!|-|:|@|\\[|\\]|\\(|\\)|\\{|\\}|_|\\*|/";
Using the character class:
String delimiters = "[-\\t,;.?!:@\\[\\](){}_*/]";
As you can see some of the characters must be escaped as they are regex metacharacters.
