public class mainCanvas extends Canvas{
int width=getWidth();
int height=getHeight();
}
我要在非继承Canvas类中调用
width和height的值
要怎么调用
给出具体代码
[解决办法]
public class mainCanvas extends Canvas{
public static int width=getWidth();
public state int height=getHeight();
}
public class otherClass extends MIDlet
{
public void startApp(){
System.out.println(mainCanvas.width);
}
public void pauseApp(){}
public void destroyApp(boolean bl){
}
}
[解决办法]
//#if "ScreenSize " == "240x320 "
int width = 240;
int height = 320;
//#else
//#int width = 176;
//#int height = 208;
//#endif
用polish编译
[解决办法]
class Canvas{
private int width = 1;
private int height = 2;
public int getWidth(){
return width;
}
public int getHeight(){
return height;
}
}
class mainCanvas extends Canvas{
int width=getWidth();
int height=getHeight();
}
public class Test {
public static void main(String[] args) {
mainCanvas a = new mainCanvas();
System.out.println( "width: "+a.width + " height: "+a.height);
}
}
