May 1, 2022 · We cannot print array elements directly in Java, you need to use Arrays.toString() or Arrays.deepToString() to print array elements. Use toString() method if you want to print a one-dimensional array and use deepToString() method if you want to print a two-dimensional or 3-dimensional array etc.

I need to print the array of objects. For example, I have an array of objects that hold objects from the "shape" class. Do I call the toString method for each object in the array, or do I code the toString method in ObjectList to print out the instance variables? If so, how do I do that?
