Let’s take a look at the algorithm first :. Arrays.toString() We know that a two dimensional array in Java is a single-dimensional array having another single-dimensional array as its elements. If you compare the for loop and for-each loop, you will see that the for-each method is … java String array works in the same manner. Let’s explore the description of these methods.
