At each iteration, find the index of the current row and column as row = i / M and column = i % M respectively. The Iterator … Here array is the name of the array itself. 1. If the condition is true, the loop will start over again, if it is false, the loop will end. You can then get each element from the array using the combination of row and column indexes. Then using for loop array elements are stored in an integer array “arrNum”. For this, we will use toString() method of Arrays class in the util package of Java. Any help or tips would be greatly appreciated! This loop can be used when only access is desired.
