Answer 2

Ball has to move up and down continuously in a straight line

Answer 3

You set your jframe size to 500 x 500, so you need to know when it y reaches the boundary of the jframe. When it does reach the boundary, change directions. You might want to offset the boundary to compensate for the radius of the ball.

Answer 4

U need velocity and work with the y axis since its up/down + u need an actionlistnner
