    copied!<p>First off, rest assured that I've read every Oracle Java article &amp; tutorial about 6 times now, so if you can help, you'll have to do better than providing a link to an Oracle page. Sorry if that sounds rude.</p> <p>Apparently I don't know how Strings work. I'm trying to get 4 jButtons to send their value to a string when pushed, so that only the last button that was pushed will record its (name, text, whatever works) in a string or value, so that I can concatenate that value to a jLabel's message.</p> <p>So there's 2 problems here, I must not have the "Status" buttons set up right, and then I need to be able to take the value and put it in the jLabel.</p> <p>You can see where I'm stuck by looking at this screenshot: <a href="http://krisbunda.com/gui2.png" rel="nofollow noreferrer">http://krisbunda.com/gui2.png</a></p> <p>See where it says "null" instead of the value of 1 of 4 "status" buttons ("Shipped" or "Loaded", etc.)</p> <pre><code> private void shippedButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: StringBuilder status = new StringBuilder(loadedButton.getText()); } private void loadedButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: StringBuilder status = new StringBuilder(loadedButton.getText()); } private void outReadyButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: StringBuilder status = new StringBuilder(outsideReadyButton.getText()); } private void outNotReadyButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: StringBuilder status = new StringBuilder(outsideNotReadyButton.getText()); } private void enterButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: Confirmation.setVisible(true); Confirmation.setBounds(300,200,900,400); Confirmation.setModal(rootPaneCheckingEnabled); confirmationLabel.setText("You are about to send this message:" + "\n #" + display.getText()+ " is currently " + status); } private void confirmationNoButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: Confirmation.dispose(); } </code></pre> <p>Any help is greatly appreciated.</p> <p><strong>EDIT:</strong></p> <p>Thanks for the help, here's the workaround I figured out for the "new line" issue: I used 2 JLabels. <img src="https://i.stack.imgur.com/lQYO5.png" alt="GUI for JLabel new line"></p> <p>and coded like so:</p> <pre><code> private void enterButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: Confirmation.setVisible(true); Confirmation.setBounds(200,300,1000,400); Confirmation.setModal(rootPaneCheckingEnabled); confirmationLabel1.setText("You are about to send this message:"); confirmationLabel2.setText("PS# " + display.getText()+ " is currently " + status); } </code></pre> <p>and here's a snippet of code to illustrate the fix answered by "Hovercraft full of eels":</p> <p><strong>1.) add non-local variable/string:</strong></p> <pre><code>public class PlanterStatusUI extends javax.swing.JFrame { /** Creates new form PlanterStatusUI */ public PlanterStatusUI() { initComponents(); } public String status = new String(); { } </code></pre> <p><strong>2.) change button code:</strong></p> <pre><code> private void shippedButtonHandler(java.awt.event.ActionEvent evt) { // TODO add your handling code here: status = shippedButton.getText(); } </code></pre>
