Adding JPanel to JFrame

java, jframe, jpanel, swing

Solution

public class Test{

Test2 test = new Test2();
JFrame frame = new JFrame();

Test(){
...
frame.setLayout(new BorderLayout());
frame.add(test, BorderLayout.CENTER);
...
}

//main
...
}

//public class Test2{
public class Test2 extends JPanel {

//JPanel test2 = new JPanel();

Test2(){
...
}

Problem

I have a program in which a JPanel is added to a JFrame: ``` public class Test{ Test2 test = new Test2(); JFrame frame = new JFrame(); Test(){ ... frame.setLayout(new BorderLayout()); frame.add(test, BorderLayout.CENTER); ... } //main ... } public class Test2{ JPanel test2 = new JPanel(); Test2(){ ... } } ``` I get an error asking me to change type of 'panel' to 'component'. I do I fix this error? It wants me to do: Component panel = new Component();
