In this Java array tutorial, we will see examples of a printing string array, integer array, byte array and a two-dimensional array in Java. The same is true with deepToString(), which is used to print two-dimensional arrays in Java. These methods are overloaded, much like () method to accept all primitive types, which means a different method is called if you pass a boolean array, and a different one is called when you print integer array. ![]() Here we have toString() and deepToString() method to print array in Java. To print Java array in a meaningful way, you don't need to look further because your very own Collection framework provides lots of array utility methods in class. All it prints is This is not at all useful for anyone who is interested in seeing whether an array is empty or not, if not then what elements it has etc. Have you tried printing arrays in Java before? What did you do? just passed an array to println() method and expecting it prints its elements? Me too, but surprisingly array despite being Object and providing a length field, doesn't seem overriding the toString() method from class. Use toString() if you want to print a one-dimensional array and use deepToString() method if you want to print a two-dimensional array. You cannot print array elements directly in Java, you need to use Arrays.toString() or epToString() to print array elements.
