concatenation, like "jButton"+ i, where (i) = 1,2,3... i use netbeans, and it creates the code for the buttons and text fields automatically, now can i make a method to read all the contents of these fields by a looplike this (((for example)))for (i=1;i

You can't do symbolic references like you're trying to do in Java, but you could make an array that has references to the textfields: JTextField fields[] = {jTextField1, jTextField2, jTextField3}; then iterate through the array. Then if you need to add more textfields you can just change the array initialization and keep the same loop.
