Thread: rotate in java

in paint method am drawing two rect but i want to rotate the 1st rect.

....
public void paint(...)
{
...
       g2d.translate(180, -50); //rotate
      g2d.rotate(Math.PI/4);
 
g.drawRect(); //roate
 
//i think i need to rotate the screen back? 
//if so than how to do this?
 
g.drawRect();//dont roate
}

//i think i need to rotate the screen back?
//if so than how to do this?

You can do the second rotation the same way you did the first.

i just change some stuff. the problem is that the 1st rect x, y, postion is getting messed up. iam not sure why. this look righ tto me.

///paint method
     Graphics2D g2d = (Graphics2D) g;
        AffineTransform saveAT = g2d.getTransform();
 
          g2d.translate(x+(width/2), y+(height/2));   //set orgin in rect middle
          g2d.rotate(Math.PI/4);                      //rotate
 
            g.drawRect(x,y,width,height);   //rotate this rect
 
            g2d.setTransform(saveAT); //rotate back
 
            g.drawRect(...);  //dont rotate this rect

Perhaps you could post a SSCCE to illustrate the problem - not code with all your program logic, but something brief and compilable that shows the problem. It also might pay to explain what you mean by "messed up". That is, describe what the output should be as well as what does appear.

Personally I would call drawRect() using the variable g2d - I just think the intent is clearer, but it comes to the same thing.
