Method 2: Using length() Method to find Java Array Size
With the help of the length variable, we can obtain the size of the array.
Examples: int size = arr[].length; // length can be used // for int[], double[], String[] // to know the length of the arrays.17 juil. 2023How to list integer array length in Java?
The length of an ArrayList in Java can be found using the size() method of the ArrayList class, with the syntax int size = arrayList. size(); .
This method returns the number of elements present in the ArrayList.
In this example, we create an ArrayList list and add a single element 'Hello' to it.To find the length of the array, you need to divide the total amount of memory by the size of one element - this method works because the array stores items of the same type.
So, you can divide the total number of bytes by the size of the first element in the array.
