What class is the split () method a member of?
The string split() method breaks a given string around matches of the given regular expression. After splitting against the given regular expression, this method returns a string array. Show
Input String: 016-78967 Regular Expression: - Output : {"016", "78967"} Following are the two variants of the split() method in Java: 1. Public String [] split ( String regex, int limit)Parameters:
Returns: An array of strings is computed by splitting the given string. Exception Thrown: PatternSyntaxException – if the provided regular expression’s syntax is invalid. The limit parameter can have 3 values:
Here’s how it works:
Following are the Java example codes to demonstrate the working of split() Java

2. public String[] split(String regex)This variant of the split method takes a regular expression as a parameter and breaks the given string around matches of this regular expression regex. Here, by default limit is 0. Parameters: regex – a delimiting regular expression Returns: An array of strings is computed by splitting the given string. Exception Thrown: PatternSyntaxException – if the provided regular expression’s syntax is invalid. Here are some working example codes: Java

Output Geeks Geeks Students It can be seen in the above example that the pattern/regular expression “for” is applied twice (because “for” is present two times in the string to be split) Example 3: Java
Example 4: Java
Example 5: Java
In the above example that trailing empty strings are not included in the resulting array arrOfStr. Java
In the above example, the trailing spaces (hence not empty string) become a string in the resulting array arrOfStr. Java
Output word1 word2 word3 word4 word5 word6 In the above example, words are separated whenever either of the characters specified in the set is encountered.

What is the function of the asterisk (*) in regular expressions?In regular expressions, asterisk (*) means “match zero or more of the preceding character.” To make a “wildcard” (that is, an expression that matches anything) with regular expressions, you must use '. *' (dot asterisk). This expression means, “match zero or more of any character.”
What symbol S is used to separate multiple exceptions in one catch statement?Starting from Java 7.0, it is possible for a single catch block to catch multiple exceptions by separating each with | (pipe symbol) in the catch block. Catching multiple exceptions in a single catch block reduces code duplication and increases efficiency.
Which statement determine that Java is a directory?isDirectory() method would return true only if the file exists and it is an directory. If the file given in the path does not exists then also it return false. So it isDirectory() would return false if the path given does not exists or it exists but it is not a directory...
What are basic regular expression patterns give brief answer for each with example?Regular expression is not a library nor is it a programming language. Instead, regular expression is a sequence of characters that specifies a search pattern in any given text (string). A text can consist of pretty much anything from letters to numbers, space characters to special characters.
