and string. I am confused all together how it works. Code is suppose to accept an integer from user, go thru the array and find the element of that array and display in a textfield. It also has to handle 2 specific exceptions. Can someone please tell me what it is suppose to look like. Thank int cannot be dereferenced java meaning you.. int cannot be dereferenced-line 53 //import java.lang.*; public class showElement implements ActionListener{ public void actionPerformed(ActionEvent e){ randomNumber = new int [100]; for (int x = 0; x < randomNumber.length; x++) randomNumber[x] = (int)(Math.random() * 1000); String inputString; inputString=valueField.getText(); try{ valueField.setText(randomNumber[Integer.parseInt(inputString)].toString());//error section } catch (IndexOutOfBoundsException ex){ valueField.setText("Out of bounds"); } catch (NumberFormatException ex){ valueField.setText("Not a Integer."); } } } Kurt Van Etten Ranch Hand Posts: 98 posted 5 years ago 1 Hi Collete, and welcome to the Ranch! The error you're getting, in line 17 of the code excerpt you posted, is because you're trying to call the toString() method on an int (since that's what's stored in the array), and int is a primitive type. There are several ways you could convert the int to a String: for example, you could concat it with an empty string to have it implicitly converted, or you could use the static Integer.toString() method to explicitly convert it .

I keep receiving cannot be the same error: int cannot be dereferenced I have a text field where the user inputs an integer and what I'm trying to do is receive that input and store it in a variable. The text field's variable is pricePay. I could give more information if needed, am I putting this line of code in the wrong place? am I missing something? private void pricePayActionPerformed(java.awt.event.ActionEvent evt) { int pricePay = Integer.parseInt(pricePay.getText()); } integer int gettext cannot be dereferenced parseint share|improve this question edited Jan 20 '14 at 14:24 Maroun Maroun 59.1k15104172 asked Jan 20 '14 at 14:14 user3215367 61 1 you are calling a local variable (int pricePay) with the same name of the text field pricePay. That line is ok per-se, but in following lines you will be acting on the integer, not on the text field. –Stefano Sanfilippo Jan 20 '14 at 14:16 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote When you write int pricePay = Integer.parseInt(pricePay.getText()); ↑ an int Then pricePay becomes an int, it'll hide the data member pricePay. Since int is primitive, it doesn't have any methods, including getText(), hence the error "int cannot be dereferenced". You can do: int pricePay = Integer.parseInt(this.pricePay.getText()); ↑ Or (better) change the name of the variable you're declaring in the method. share|improve this answer answered Jan 20 '14 at 14:19 Maroun Maroun 59.1k15104172 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

I saw couple of similar questions but still cannot figure out my own case. Here is the complete codes: package inclass; class OneInt { int n; OneInt(int n) { this.n = n; } @Override public boolean equals(Object that) { if (that instanceof OneInt) { OneInt thatInt = (OneInt) that; return n.equals(thatInt.n); // error happens here } else { return false; } } public static void main(String[] args) { Object c = new OneInt(9); Object c2 = new OneInt(9); System.out.println(c.equals(c2)); System.out.println(c.equals("doesn't work")); } } Thank you very much for helping me with this little trouble. java share|improve this question edited Apr 7 '13 at 0:08 paulsm4 57.2k67192 asked Apr 7 '13 at 0:04 Tian 3313 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted equals is a method of a class. int is a primitive, not a class.
