问题描述
我有一个将JPanel添加到JFrame的程序:
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(){
...
}
}
我收到一条错误消息,要求我将面板"的类型更改为组件".我要解决此错误吗?它想让我做:组件面板= new Component();
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();

public class Test{
Test2 test = new Test2();
JFrame frame = new JFrame();
