Clear out an int

how do i completely erase any value from an integer vairable?

this does not work:

Code:

---

theint = null;

---

I didn't notice that working in c/c++ except when using NULL instead of null, but in Java, you might use an Integer object which wraps an int primitive; then you can set the Integer object to null.

Yes VirtuallyVB is right. The literal value NULL is used to
identify the fact that an Object is not assigned to a variable.... It can be used with any variable that is not
of a primative data type.... and int is a primative data type.

I was wondering this too, I was trying to use it to ckeck a text field to see if the user did not enter any input when a button is pressed.

TextField
public String getText()

String
public int length()

Code:

---

TextField aTextField;
...
int theint = aTextField.getText().length();

if(theint == 0){
 //Then the user did not enter any input when a button is pressed.
}
