Image resizing using Java code

We will see how to re-size image using Java program. Below program will explains you about resizing image using Java code. Method resizeMyImage() will take necessary parameters like re-size image name, original image and resize image sizes (width and height).

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class ImageResize {
    public static void main(String[] args) {
        // resize_image_name, original_image, resize_image_sizes 
        new ImageResize().resizeMyImage("e:\\rat_resized.jpg", "e:\\rat.jpg", "200", "93");
    }
    
    private void resizeMyImage(String resizeImg, String filePath, String w, String h){
        if(new File(filePath).exists()){
            imageResize(filePath, Integer.parseInt(w) , Integer.parseInt(h), resizeImg);
            System.out.println("Resize completed....");
        }else{
            System.out.println("Original file not exist....");
        }        
    }
    
    public void imageResize(String oriImgUrl, int width, int heigth, String saveLocFilePath){
        try {            
            File f = new File(oriImgUrl);
            BufferedImage image = ImageIO.read(f);
            BufferedImage resizeImage = resize(image, width, heigth);
            ImageIO.write(resizeImage, "jpg", new File(saveLocFilePath));            
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }
    
    private static BufferedImage resize(BufferedImage image, int width, int height) {
        BufferedImage resizedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        Graphics2D g = resizedImage.createGraphics();
        g.drawImage(image, 0, 0, width, height, null);
        g.dispose();
        return resizedImage;
    }
