Question

I am fresher in Netbeans . I have a small assignment related Netbeans . I want to show some names in JTextfield (for example "abcd","ijkl","mnop" etc as next by next) and it must show one by one . I had create some code which not working properly. I am looking some helps related to it. Please mention as full code here that I can understand in future.I do not know how to create it. So i am done it some another ways. But showing error message. My code is as follows.

 private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:

    String s[]={"abcd","ijkl","mnop" } ;


 for(int d=0; d<s.length;d++)



  jTextField1.setText(""+s);

}                           

Answer 1

Both these variables should be inside of your class but outside of any method.

String s[]={"abcd","ijkl","mnop" } ;
int i=0;

In action performed method

if(i>=s.length)
   i=0;

jTextField1.setText(s[i]);
i++;

For the first click, display abcd .

Next click, display ijkl .

Next click, display mnop .

But I didn't check it. Just try it. It will works.
