java屏幕快速截图,java代码实现截图功能(屏幕截图)
代碼如下:
import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;

public class Test

}

}
/****************************************************************

//拷貝屏幕到一個BufferedImage對象screenshot
BufferedImage screenshot = (new Robot()).createScreenCapture(new

//根據(jù)文件前綴變量和文件格式變量，自動生成文件名
String name=fileName+String.valueOf(serialNum)+"."+imageFormat;
File f = new File(name);
System.out.print("Save File "+name);
//將screenshot對象寫入圖像文件
ImageIO.write(screenshot, imageFormat, f);

}
}
