There is no size() method available with the array. But there is a length field available in the array that can be used to find the length or size of the array.
array.length: length is a final variable applicable for arrays. With the help of the length variable, we can obtain the size of the array.
int size = arr.length; // length can be used // for int, double, String // to know the length of the arrays.
Below is the illustration of how to get the length of array in Java using length variable:
