.length

In Java, the .length property is used to determine the length or size of an array. It is a built-in property for arrays and returns an integer value that represents the number of elements in the array.

Syntax

The syntax of the .length property is the following:

arrayName.length;

• arrayName: The name of the array to call .length on.

Example

The example below uses the .length property to determine the size of an array:

int[] numbers = {1, 2, 3, 4, 5};
int length = numbers.length;
System.out.println("Length of the array is" + length)

In this example, the numbers array contains five elements, and the .length property returns the value 5, which is assigned to the length variable.

Output for the above code will be:

Length of the array is 5
