You can’t assign a float value to an int variable because some of the information will be lost. For the same reason, you can’t pass a float value to a method whose argument is declared as an int. (your question is rather unclear due to the incorrect use of terminology, but I think you are … Read more
Position of the first circle is described as x1 = x1_0 + vx1 * t y1 = y1_0 + vy1 * t where x10 is initial x-coordinate, vx1 is x-component of velocity vector, t is time. Make similar expression for the second circle center, build expression for squared distance and find time when squared distance … Read more
The code that checks bouncing is off by a bit. First of all, ball.getCenterX()+ball.getRadius() is effectively the right side of the ball, and that’s the only part that you’re comparing to the paddle’s location. That means that the effective paddle location is off by an amount equal to the radius of the ball. You can … Read more
