java如何获取image_JAVA获取Image的几种方式

一.使用javax.imageio包下ImageIO类的read()方法

1.Image image = ImageIO.read(new FileInputStream(“文件路径”));

2.Image image = ImageIO.read(new File());

3.Image image = ImageIO.read(new URL()));

File file = new File("images\\back2.png");

Image image = ImageIO.read(new FileInputStream("images\\back2.png"));

image = ImageIO.read(file);

URL url = new URL("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1560583876537&di=58273c7d7c5698e55c1e3f81a5583365&imgtype=0&src=http%3A%2F%2Fimage20.it168.com%2Fpicshow%2F900x675%2F20111124%2F2011112416144308103.jpg");

image = ImageIO.read(url);

二.使用Toolkit类下的getImage()方法

1.Toolkit.getDefaultToolkit().getImage(“图片路径”)；

Image image = Toolkit.getDefaultToolkit().getImage("images/a.jpg");

三.使用ImageIcon类的getImage()

1.new ImageIcon("图片路径).getImage()；

Image image = new ImageIcon("images\\a.png")).getImage()
