Which statement is true regarding the first component of an array?

The first component of an array in Java is indeed accessed using index 0. This is a fundamental aspect of how arrays are structured in Java and many other programming languages. In an array, the indexing system starts at zero, meaning that the first element is located at the zeroth index.

For instance, if you have an array declared as int[] numbers = {10, 20, 30};, you would access the first element (which is 10) by referring to it as numbers[0]. This zero-based indexing allows for efficient memory access and manipulation within the array.

In contrast, other statements about accessing array elements do not hold true within the context of Java. Accessing by name implies that you could reference an array without specifying an index, which would not yield a specific element. The notion that array components are stored at random memory locations is incorrect given that elements in an array are stored in contiguous memory locations, allowing for predictable access patterns. Additionally, the requirement for a special keyword to access array components does not apply; simple bracket notation suffices for direct access to array elements.
