What does it mean by INT Cannot be dereferenced?

How do you convert a number to an array in Java?

If you need a string array, then simply convert the number to a string and grab its characters with the charAt() method (or substring()) of the String class. Else, you need to use divison by 10 repeatedly to find the digit values (for example, 34567 / 10000 = 3, then go on with the rest, 4567 / 1000 = 4, and so on).

How do you compare strings in Java?
