Arrays in Java

Java provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Premitive Arrays in Java:

public class Arrays {
	public static void main(String[] args) {
		//Array Of Type int
		int[] intValues = {2, 4, 6, 8, 10};
		System.out.println("Array one: of type int");
		System.out.println(intValues[0]);
		System.out.println(intValues[1]);
		System.out.println(intValues[2]);
		System.out.println(intValues[3]);
		System.out.println(intValues[4]);

		//Array Of Type double
		double[] floatValues = {1.2, 2.3, 3.1, 4.5};
		System.out.println("Array two: of type double");
		System.out.println(floatValues[0]);
		System.out.println(floatValues[1]);
		System.out.println(floatValues[2]);
		System.out.println(floatValues[3]);

		//Array Of Type String
		String[] stringValues = {"East",  "West", "North", "South"};
		System.out.println("Array three: of type string");
		System.out.println(stringValues[0]);
		System.out.println(stringValues[1]);
		System.out.println(stringValues[2]);
		System.out.println(stringValues[3]);

		//Array Of Type char
		char[] charValues = {'A', 'B', 'C', 'D'};
		System.out.println("Array three: of type string");
		System.out.println(charValues[0]);
		System.out.println(charValues[1]);
		System.out.println(charValues[2]);
		System.out.println(charValues[3]);

		//Array Of Type boolean
		boolean[] booleanValues = {true, false};
		System.out.println("Array three: of type string");
		System.out.println(booleanValues[0]);
		System.out.println(booleanValues[1]);

	}
}

Output:

Array one: of type int
2
4
6
8
10
Array two: of type double
1.2
2.3
3.1
4.5
Array three: of type string
East
West
North
South
Array three: of type string
A
B
C
D
Array three: of type string
true
false
