Is there any way to detect collision between an oval and a line in java. I am making a game where the user navigates a rocket through a "cave" where the "cave" is made up of lines and i need someway to detect collision. The code is below
@Override //draws all the lines and ship
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2=(Graphics2D) g;
Rectangle r=new Rectangle();
g2.setStroke(new BasicStroke(3));
g2.drawLine(0, getHeight()-(getHeight()/6), getWidth()/6, getHeight()-(getHeight()/6));
g2.drawLine(getWidth()/6, getHeight()-(getHeight()/6), getWidth()/6, getHeight()-getHeight()/4);
g2.drawLine(getWidth()/6, getHeight()-getHeight()/4, getWidth()/6+getWidth()/10, getHeight()-getHeight()/4);
g2.drawLine(getWidth()/6+getWidth()/10, getHeight()-getHeight()/4, getWidth()/6+getWidth()/10, getHeight()-getHeight()/12);
g2.drawLine(getWidth()/6+getWidth()/10, getHeight()-getHeight()/12, getWidth()/2, getHeight()-getHeight()/12);
g2.drawLine(getWidth()/2, getHeight()-getHeight()/12, getWidth()/2, getHeight()-getHeight()/4);
g2.drawLine(getWidth()/2, getHeight()-getHeight()/4, getWidth()/3+getWidth()/15, getHeight()-getHeight()/4);
g2.drawLine(getWidth()/3+getWidth()/15, getHeight()-getHeight()/4, getWidth()/3+getWidth()/15, getHeight()-getHeight()/3);
g2.drawLine(getWidth()/3+getWidth()/15, getHeight()-getHeight()/3, getWidth()/2+getWidth()/7, getHeight()-getHeight()/3);
g2.drawLine(getWidth()/2+getWidth()/7, getHeight()-getHeight()/3, getWidth()/2+getWidth()/7, getHeight()-getHeight()/6);
g2.drawLine(getWidth()/2+getWidth()/7, getHeight()-getHeight()/6, getWidth()-getWidth()/4 , getHeight()-getHeight()/6);
g2.drawLine(getWidth()-getWidth()/4, getHeight()-getHeight()/6, getWidth()-getWidth()/4, getHeight()-getHeight()/4);
g2.drawLine(getWidth()-getWidth()/4, getHeight()-getHeight()/4, getWidth()-getWidth()/7, getHeight()-getHeight()/4);
g2.drawLine(getWidth()-getWidth()/7, getHeight()-getHeight()/4, getWidth()-getWidth()/7, getHeight()-getHeight()/8);
g2.drawLine(getWidth()-getWidth()/7, getHeight()-getHeight()/8, getWidth(), getHeight()-getHeight()/8);
g2.setColor(Color.YELLOW);
g2.fillRect(getWidth()-getWidth()/7, getHeight()-getHeight()/8, getWidth()/7, 20);
g2.rotate(Math.toRadians(theta),rocketx+10, rockety+20);
g2.setColor(Color.orange);
g2.fillOval(rocketx, rockety, 20, 40);//draws ship
}
public void initialRocket(int x, int y) {//inital position of ship
rocketx=x/12-10;
rockety=y-(y/4)-20;
}

You need to keep the rocket and the cave in memory, probably as special objects. (Maybe a Rocket class and Cave, which could be a collection of e.g., walls and stalagmites or what you have.) The Rocket knows its position and dimensions, as do the parts of a cave. Using that information you can check for a collision. From just drawing the lines you it would be quiet hard to figure out whether a collision happened.
