Example 2: how to declare array java

Example 3: creating array java
int[] intArray = new int[]{ 1,2,3,4,5,6,7,8,9,10 }
Example 4: how to create an array in java

Example 5: how to declare an array in java
An array is an ordered collection of elements of the same type, identified by a pair of square brackets [].
To use an array, you need to:
1. Declare the array with a name and a type. Use a plural name for array, e.g., marks, rows, numbers. All elements of the array belong to the same type.
2. Allocate the array using new operator, or through initialization, e.g.
int[] marks;
int marks[];
marks = new int[5];
int[] factors = new int[20];
int[] numbers = {11, 22, 33, 44, 55, 66};
Example 6: array in java
int[] age = new int[3];
age[0] = 1;
age[1] = 3;
age[2] = 6;
for (int i=0; i < 3; i++)
System.out.println(age[i]);
int[] num = {3,3,5};
System.out.println(num[0]);
