BufferedImage的两种用法

方法一：使用绝对路径

import java.awt.image.BufferedImage;
import java.io.FileInputStream;

import javax.imageio.ImageIO;

public class test {
    public static void main(String[] args)
    {
        String s="C:\\Users\\1314\\Desktop\\AriplaneWar\\src\\image\\start.png";
        try{
            BufferedImage image=ImageIO.read(new FileInputStream(s));
            System.out.println(image.getWidth());
            System.out.println(image.getHeight());   
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }  
         
    }
}

方法二：使用相对路径

import java.awt.image.BufferedImage;

import javax.imageio.ImageIO;

public class test {
    public static void main(String[] args)
    {  
        try{
            BufferedImage image = ImageIO.read(test.class.getResource("start.png")); 
            System.out.println(image.getWidth());
            System.out.println(image.getHeight());

        }
        catch(Exception e)
        {
            e.printStackTrace();
        } 
    }
}

两种方法都可以得到正确结果
