set title to JFrame

问题

I am new to Java. My problem is that I have a class names MyClassExp. I have extended it from JFrame. Inside the class, I initiate an object of another class named TabbedFrame. TabbedFrame also extends a class DemoFrame . In DemoFrame, I have the title of the page set using keyword 'super' like:

super("Some Title");

Now when I run my MyClassExp, even after creating a JFrame as:

new JFrame("New Title"); 

I'm still getting the same title i.e Some Title. Is there any way to solve this problem? I've tried a lot to solve it but failed :'(

回答1:

Use the API method public void setTitle(String title).

回答2:

- Inside the MyClassExp class's constructor use this.setTitle(String title) method.

回答3:

Just use setTitle("yourTitleName");

for example:

setTitle("Currency Converter");
textField.addKeyListener(this);
combo.addItemListener(this);
label.addMouseListener(this);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
