find length of array java

Int[] array = {1,2,3};
int lengthOfArray = array.length; /** Finding the length of the array and storing it */
System.out.println(String.valueOf(lengthOfArray)); /** Should print out 3, String.value Of() is optional as printLn does this automatically. */let coolCars = ['ford', 'chevy'];
//to find length, use the array's built in method
let length = coolCars.length;
//length == 2.
