[英]java.AWT - setSize() method
I am facing an issue using setSize() method in the below program.我在下面的程序中使用 setSize() 方法遇到问题。
Error : The method setSize(int,int) is not defined for the type frame.
错误:未为类型框架定义 setSize(int,int) 方法。
When I see Java API, "Class Frame" has this Method inherited from class java.awt.Window.当我看到 Java API 时,“类框架”具有从类 java.awt.Window 继承的此方法。 As i have instantiated the Frame class, this object should have setSize() method as Frame is derived class of Window.
因为我已经实例化了 Frame 类,所以这个对象应该有 setSize() 方法,因为 Frame 是 Window 的派生类。 Why am I getting this error then?
为什么我会收到这个错误? How can a derived class doesnt contain its superclass method?
派生类如何不包含其超类方法?
public class AwtPrac{
public static void main(String[] args) {
Frame fm = new Frame("Java Programm");
Button b= new Button ("Click Here");
fm.add(b);
fm.setVisible(true);
fm.SetSize(300,300);
fm.dispose();
}
}
Take this code拿这个代码
import java.awt.Frame;
public class AwtPrac {
private static void init(){
Frame fm = new Frame("Java Programm");
fm.setTitle("AwtPrac");
fm.setSize(300,300);
fm.setVisible(true);
}
public static void main(String[] args) {
init();
}
}
