An array is a fixed number of elements of the same type stored sequentially in memory. Therefore, an integer array holds some number of integers, a character array holds some number of characters, and so on. The size of the array is referred to as its dimension. To declare an array in C++, we write the following: type arrayName[dimension];

String array[] = {"Hello, World", "Hi there, Everyone", 6}; We could declare the array as containing Object instead of String, and override Java’s type system. But, that’s not how any experienced Java developer uses the language. In Python, we don’t have to provide a type when we declare the array and can put whatever we want in it.
