How do you define the length of an array in Java?
In Java, you can define the length of an array using the following syntax:
- Specify the length of an array when declaring it.
int[] array = new int[5];
The above code defines an integer array with a length of 5.
- Longitudinal measurement.
int[] array = {1, 2, 3, 4, 5};
int length = array.length;
The above code defines an integer array with 5 elements and retrieves the length of the array using the length property. In this case, there is no need to explicitly specify the length of the array.
It should be noted that once an array is created, its length is fixed and cannot be changed. If there is a need to dynamically adjust the length of an array, consider using the ArrayList class or other similar data structures.
