In java to split string, we use split function of String class. Example : We want to split string java:advanced:cpp based on : character. We will use it like this-               String value=  "java:advanced:cpp"               String[] resultArray = value.split(":")           Resultant array will have following values: "java","advanced","cpp" Split function takes input as regex expression. So if we want to split string based on some special character, then it will not be similar like we did before. Example:                    String value = "Java [ advanced [ cpp ";                    String[] resultArray = value.split("[");   this will throw a runtime exception PatternSyntaxException . We are trying to split the string based on "[" character, which is open square bracket for a regex expression. So it consider this as open bracket and it looks for closing bracket, So it throws the exception.
