Java Regular Expression: Splitting a String with ':'

Rom wrote the following regular expression program. What will be the output?

Pattern myPattern = Pattern.compile(":");
String[] split = myPattern.split("one:two:three:four:", 2);
for (String element : split) {
    System.out.println("element = " + element);
}

Output:

element = one
element = two:three:four:

Explanation:

• Pattern.compile(":") creates a regular expression pattern that matches the colon character (':').
• myPattern.split("one:two:three:four:", 2) splits the string "one:two:three:four:" into an array of strings using the colon as the delimiter. The second argument 2 limits the split to a maximum of two elements.
• The loop iterates over the resulting array and prints each element.

**Therefore, the correct output is:

element = one element = two:three:four:**

This demonstrates how to use regular expressions in Java to split strings based on a specified delimiter and how to control the number of resulting substrings.
