java-programmer, why it doest draw ??? in the below short write
i try to write an Thread examle that try to draw lines in every second
from (0,0) to (x, y).
x and y are random between 0..255
with first come to tWork (Thread) it draws, but next second and next
seconds it doesnt do any thing.
g and gr are the same and initalized
i cheked them with this command :
System.out.println(gr.equals(g)); //it prints "true"

question is why it doesnt draw line after second 1 ?

}

public void run()

while (true)
{
x = (int)(Math.random()*255);
y = (int)(Math.random()*255);
gr.drawLine(0, 0, x, y);
