In Java, arrays don't override toString(), so if you try to print one directly, you get the className+'@'+ the hex of the hashCode of the array, as defined by Object.toString():
int[] intArray = new int[] {1, 2, 3, 4, 5};System.out.println(intArray); // Prints something like '[I@3343c8b3'But usually, we'd actually want something more like [1, 2, 3, 4, 5]. What's the simplest way of doing that? Here are some example inputs and outputs:
// Array of primitives:int[] intArray = new int[] {1, 2, 3, 4, 5};// Output: [1, 2, 3, 4, 5]// Array of object references:String[] strArray = new String[] {"John", "Mary", "Bob"};// Output: [John, Mary, Bob]
