Hi Yogesh, Same is the case with me. I'm a python developer. What Piyush saying is right. For your reference:
https://www.tutorialspoint.com/opencv/opencv_rotation.htm This is the guide to rotate the image. You can explore OpenCV for java on google. You can find a solution for everything which we have mentioned earlier. OpenCV is the major library that is used to modify the images.
