Leetcode 4 Median of Two Sorted Arrays Java Solution

There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). You may assume nums1 and nums2 cannot be both empty. Example 1: nums1 = [1, 3] nums2 = [2] The median is 2.0 Example 2: nums1 = [1, 2] nums2 = [3,…… Continue reading Leetcode 4 Median of Two Sorted Arrays Java Solution

HashMap In Java With Example

Here we will learn about the Java HashMap class with an example along with the functions provided by the Java HashMap class which resides in the Java util package. The Java HashMap class implements the Map interface, which is used for storing key-value pairs. HashMap is represented as HashMap<Key, Value> or HashMap<K, V>, the key…… Continue reading HashMap In Java With Example

Resilience4j Circuit Breaker With Spring boot

What is a Circuit Breaker pattern? The circuit breaker pattern is something that can prevent from repeatedly trying to call a service or a function that will likely fail and save CPU cycles. It is pretty common for a software service to call remote software service and the remote service can fail or not respond…… Continue reading Resilience4j Circuit Breaker With Spring boot

Arrays In Java With Example

The array is a data structure provided by Java which holds elements of the same data type with a fixed size.An array can hold elements/ values of the same data type, an example being we can create an array that can store 100 elements of type either int/String/char etc.. We can not have array hold…… Continue reading Arrays In Java With Example

Java ArrayList With Example

ArrayList is a resizable implementation of List interface, ArrayList can also be called as a dynamic Array. Like Array, ArrayList stores similar data type elements which can increase its size dynamically.ArrayList cannot store primitive data types like int and char, it can only store non-primitive data types like Integer, String, etc..The index of the ArrayList…… Continue reading Java ArrayList With Example

Netflix Eureka Server And Client Setup With Spring Boot

Overview We will set up a Eureka server (service registry used to register multiple services/microservices).We will set up multiple Eureka clients(REST services that register to Eureka Server).We will do client-side load balancing and service discovery through Eureka. Setting up Eureka Server The dependency required to set up a eureka server is “spring-cloud-starter-netflix-eureka-client” along with spring-boot-starter-parent.…… Continue reading Netflix Eureka Server And Client Setup With Spring Boot
