The size of a String is determined by the number of characters it contains. Each character in Java is represented by two bytes (16 bits) due to the use of the UTF-16 encoding, which allows the representation of a wide range of Unicode characters. Considering the memory constraints, the ma...
The logic of this method is that we can get the array’s length by subtracting the lowest index to the highest index then adding 1. We add 1 since it is needed to include the lowest index in the array’s length. The code block below will demonstrate getting the array length of an ar...
