An array is a collection of similar types of elements stored in a contiguous memory location. The following section contains various programs on Arrays with examples like array operations, types of array, single-dimensional array, sort, and merging operations, mathematical functions on arrays, and array data structures. It also covers programs on insertion and deletions of elements in an array.
Each sample program includes a program description, Java code, and program output. All examples have been compiled and tested on Windows and Linux systems.
Here is the listing of Java programming examples on Arrays:
- Java Programs on Largest & Smallest Numbers in an Array
- Java Programs on Inserting & Deleting Elements from an Array
- Java Programs to Perform Operations on Arrays
- Java Programs on Printing the Elements of an Array
- Single Dimensional Array Programs in Java
