Here we are declaring label. Label is a widget that contains text.































































































































Hyperlink link0 = new Hyperlink("Delhi", "Delhi")































































Creating Hyperlink object named 'link0'. Hyperlink is a class or a widget that serves as an "internal" hyperlink

Java Code: To create hyperlink using GWT

package org.hyperLink.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.HistoryListener;
import com.google.gwt.user.client.History;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.Hyperlink;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.VerticalPanel;

public class HyperLinkExample implements EntryPoint, HistoryListener {

    private Label label = new Label();

    public void onModuleLoad() {
        Hyperlink link0 = new Hyperlink("Delhi", "Delhi");
        Hyperlink link1 = new Hyperlink("Mumbai", "Mumbai");
        Hyperlink link2 = new Hyperlink("Chennai", "Chennai");
        Hyperlink link3 = new Hyperlink("Banglore", "Banglore");

        String Token = History.getToken();
        if (Token.length() == 0) {
            History.newItem("Banglore");
        }
        VerticalPanel panel = new VerticalPanel();
        panel.add(label);
        panel.add(link0);
        panel.add(link1);
        panel.add(link2);
        panel.add(link3);
        RootPanel.get().add(panel);
        History.addHistoryListener(this);
        History.fireCurrentHistoryState();
    }

    public void onHistoryChanged(String historyToken) {
        label.setText("The current Link selected is: " + historyToken);
    }
}
