Defanging an IP Address

As a Systems Engineer at Tata Consultancy Services, I deliver exceptional software products for mobile and web platforms, using agile methodologies and robust quality maintenance. I am experienced in performance testing, automation testing, API testing, and manual testing, with various tools and technologies such as Jmeter, Azure LoadTest, Selenium, Java, OOPS, Maven, TestNG, and Postman.
I have successfully developed and executed detailed test plans, test cases, and scripts for Android and web applications, ensuring high-quality standards and user satisfaction. I have also demonstrated my proficiency in manual REST API testing with Postman, as well as in end-to-end performance and automation testing using Jmeter and selenium with Java, TestNG and Maven. Additionally, I have utilized Azure DevOps for bug tracking and issue management.
Given a valid (IPv4) IP address, return a defanged version of that IP address.
A defanged IP address replaces every period "." with "[.]".
LeetCode Problem - 1108
class Solution {
// Method to replace periods in IP address with "[.]"
public String defangIPaddr(String address) {
// Split the IP address into an array of strings using periods as separators
String[] addressArray = address.split("\\.");
// StringBuilder to build the defanged IP address
StringBuilder sb = new StringBuilder();
// Iterate through the addressArray
for(int i=0; i<addressArray.length; i++){
// Check if it's not the last element in the array
if(i!=addressArray.length-1){
// If not the last element, append the address element and "[.]" to StringBuilder
sb.append(addressArray[i]).append("[.]");
}
else{
// If it's the last element, just append the address element
sb.append(addressArray[i]);
}
}
// Convert StringBuilder to String and return the defanged IP address
return sb.toString();
}
}
