1. What is an Array? An array is a collection of elements stored at contiguous memory locations. All elements in an array must be of the same data type. Arrays allow random access to elements, meaning you can access any element using its index. Example: int[] arr = {1, 2, 3, 4, 5};System.out.println(arr[2]); // Output: … Read more
1. What is Java? Java is a high-level, object-oriented programming language developed by Sun Microsystems in 1995. It is platform-independent, meaning that Java programs can run on any device that has the Java Runtime Environment (JRE) installed. This is achieved through the use of Java Virtual Machine (JVM), which allows Java applications to run on … Read more
