Question

I\'m wondering if there\'s a funciton in Java that can draw a line from the coordinates (x1, x2) to (y1, y2)?

What I want is to do something like this:

Answer 1

To answer your original question, it's (x1, y1) to (x2, y2).

For example,

This is to draw a horizontal line:

g.drawLine( 10, 30, 90, 30 );

vs

This is to draw a vertical line:

g.drawLine( 10, 30, 10, 90 );

I hope it helps.
