Display the content of the array that holds the count for each digit in the string. Use http://stackoverflow.com/questions/27672486/java-error-char-cannot-be-dereferenced a format similar to the following: Example: Digit 0 showed up 4 times. Digit 1 showed up 0 times. Digit 2 showed up 1 times. Digit 3 showed up 4 times. Digit 4 showed up 0 times. Digit 5 showed up 0 times. Digit 6 showed up 0 times. Digit 7 showed up 1 times. Digit 8 showed up 0 times. Digit 9 showed up 0 times The teacher also provided us with an algorithm as a hint: set up an integer array of size 10 initialize each element to zero input string of phone number set SIZE = length of the string set up a loop to iterate SIZE times { get next character update array appropriately (for example: if the character is '7' then increment array[7] by 1. } Display BOTH using appropriate messages: the original phone number contents of the array (using a loop). Here is My code but it shows the error I mentioned when i use the equals() method, and displays a wrong answer if i use ==. Please Help. public class Phones { public static void main(String[] args) { int Num[] = {0,0,0,0,0,0,0,0,0,0}; String Phone = "703-323-3000"; int SIZE = Phone.len

Madhav Lakkapragada Ranch Hand Posts: 5040 posted 15 years ago Dereferensing means setting the reference to NULL. This way you are no longer referencing any obj. This is one way.

Frank Carver Sheriff Posts: 6920 posted 15 years ago 1 I don't agree with the explanation here. "dereferencing" actually refers to the process of getting or setting the value referred to by a reference. For example, If I say String s = "hello" then s is a reference to the actual characters. In this case I can dereference s to get the characters, but if I say, for example String s = null; then I can't cannot be dereferenced dereference s, because it does not refer to any characters - it is null! In the case of the initial question, I would imagine that the code was trying to call a method on a byte, and as byte is a primitive type which contains its own value, and not a reference to an Object, it could not be dereferenced. For example: byte b = 45; System.out.println(b.toString()); will not work (if you need to call a method, you should have used the object wrapper class Byte, instead), and neither will byte b; b[7] = 23; where the [] have inadvertently omitted from an array declaration.

Dereference is a common operation done by C++ programers. Hope this will clear Dereferencing. Michael Ernest High Plains Drifter Sheriff Posts: 7292 I like... posted 15 years ago Heya Frank - Thanks for your post. I don't use this particular term myself except by accident, partly because I've heard it used both ways with equal vigor and confidence. Judging only by the way I've most often seen it used, deferencing meaning "setting to null" seems the popular me
