How to Sort 3 Integers in Java

Use Java to sort numbers.

The object-oriented language Java is a general-purpose programming language containing packages of classes that can be used to develop programs. With Java, information of any type can be stored in data structures. A fixed amount of integers can be stored in a data structure called an "array." One way to sort the data in an array is to use methods from the Arrays class. A sorted array allows the use of more efficient search algorithms to search through the array.

Things You'll Need

• Java Runtime Environment
• Java Development Kit
• Java Development Environment

Instructions

1. Create a new file in your Java development program.

2. Type the following at the top of the file in your text editor:

   import java.util.Arrays;

   Java.util.Arrays contains a method that will be used to sort an array of integers.

3. Create an array of three integers, as in the following example:

   int[] array = new int[] {3, 1, 2};

4. Sort the array using the Arrays.sort method by typing the following:

   Arrays.sort(array);

   The Array.sort method sorts the integers in the array by ascending order.
