public class LoginFrame extends Frame{

super("计算器");
this.setSize(200,300);
this.setLocation(300,240);
this.setBackground(Color.lightGray);
this.setLayout(new GridLayout());
this.setLayout(new GridLayout(5,6));
String str[]={"MC","MR","MS","M-","M+","7","8","9","/","4","5","6","*","1","2","3","-","0",".","=","+"};
for(int i=0;i<str.length;i++)
this.add(new Button(str[i]));
this.setVisible(true);
}
public static void main(String[] args) {new LoginFrame();}
}
