This article is to share with you how to use java to achieve the game of fishing talent. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Source code sharing:

Test class:

Package game;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;import javax.swing.JFrame;/** * test class * @ author Lenovo * * / public class Client {public static void main (String [] args) throws IOException {/ / create a window JFrame gameFrame = new JFrame ("fishing talent"); / / put the pond into the interface Pool pool = new Pool (); gameFrame.setContentPane (pool) / / create window icon, absolute path BufferedImage icon = ImageIO.read (new File ("E:/New_life/fish_game/resource/images/fish07_03.png")); gameFrame.setIconImage (icon); / / set window size gameFrame.setSize (800,500); / / window location gameFrame.setLocation (10,10); / / set window non-draggable gameFrame.setResizable (false) / / set the window to close gameFrame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); / / Let the window display gameFrame.setVisible (true); / / call the method pool.action ();}}

Setting of the cannon:

Package game;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;public class Cannon {/ / cannon private BufferedImage image; / / coordinate values private int x; private int y; public Cannon () throws IOException {this.image = ImageIO.read (new File ("resource/images/barrel.png")); this.x = 420; this.y = 400;} public BufferedImage getImage () {return image } public void setImage (BufferedImage image) {this.image = image;} public int getX () {return x;} public void setX (int x) {this.x = x;} public int getY () {return y;} public void setY (int y) {this.y = y;}}

There is also a scoreboard not written, there is no start and end interface, the fishing net is static, these functions have not yet been implemented, will be updated in the future.
