Concurrency in programming is the ability to run multiple tasks simultaneously in a program. Concurrency allows for better utilization of system resources and can improve program performance. In Java, concurrency can be achieved using threads. Here is an example code in Java that demonstrates concurrency using threads: In this example, we define a class called…
Read MoreHow to implement Recursion in Java?
- 0
Recursion is a technique in programming where a function calls itself in order to repeat a set of instructions until a certain condition is met. Instead of using loops to iterate through data, recursion relies on a function calling itself repeatedly to solve a problem. Recursion is often used for problems that can be broken…

How to Implement Bubble Sort in Java?
- 0
Bubble Sort is a simple sorting algorithm that repeatedly compares adjacent elements in an array and swaps them if they are in the wrong order. The algorithm gets its name from the way smaller elements “bubble” to the top of the array. The basic idea of the Bubble Sort algorithm is as follows: Bubble Sort…
