How Does This `move()` Method Keep a Star Object Within Frame Boundaries?

提供的代码片段中的 move 方法用于更新 Star 对象的位置。它通过检查与框架边缘的碰撞来确保星星保持在框架的边界内。

这是修改后的移动方法:

public void move() {
    // Check if the star has reached the left or right edge of the frame
    if (location.x < 0 || location.x > frame.getContentPane().getWidth() - 20) {
        // Reverse the x direction of movement
        xIncr = -xIncr;
    }

    // Check if the star has reached the top or bottom edge of the frame
    if (location.y < 0 || location.y > frame.getContentPane().getHeight() - 20) {
        // Reverse the y direction of movement
        yIncr = -yIncr;
    }

    // Update the location of the star based on its speed
    translate(xIncr, yIncr);

    // Update the location of the center of the star
    location.setLocation(location.x + xIncr, location.y + yIncr);
}
