Find length or size of an Array in Java

you can determine the length or size of an array using the length property. The length property returns the number of elements in the array.

Here's an example:

int[] numbers = {1, 2, 3, 4, 5};
int length = numbers.length; // returns 5

In the example above, the numbers array has five elements. To determine the length of the array, we access the length property of the array and assign its value to the length variable.

Note that the length property is a final instance variable, which means that its value cannot be changed after the array is created. Additionally, the length property is not a method, so you don't need to use parentheses when accessing it.
