Even If I make it 100, no use. Its the same result I am getting.

Hi,
When I run the program ImageUtil1.java using JRE 1.6 ,I am getting a thumb image with good quality.
But If I change the jre version to 1.5 then the quality of the thumb image is not good.

code :

import java.awt.Graphics2D; import java.awt.Image; import java.awt.RenderingHints; import java.awt.image.BufferedImage; import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import javax.imageio.ImageIO; import com.sun.image.codec.jpeg.JPEGCodec; import com.sun.image.codec.jpeg.JPEGEncodeParam; import com.sun.image.codec.jpeg.JPEGImageEncoder; public class ImageUtil1 { public static void main (String [] args) { try { File myDicomFile = new File("D:\\thumbImages\\i1.jpg"); FileInputStream fin = new FileInputStream(myDicomFile); byte [] imageBytes = new byte[ (int) myDicomFile.length () ]; System.out.println("ImageUtil1.main() "+imageBytes.length); fin.read (imageBytes); saveThumbImage(imageBytes, "QC_i1"); } catch (Exception e) { e.printStackTrace (); } } public static void saveThumbImage(byte[] image,String fileName){ try{ Image thumb; ByteArrayInputStream bis = new ByteArrayInputStream(image); thumb = ImageIO.read(bis); int thumbWidth = Integer.parseInt("128"); int thumbHeight = Integer.parseInt("128"); int width = thumb.getWidth(null); int height = thumb.getHeight(null); BufferedImage bi = new BufferedImage(thumbWidth,thumbHeight,BufferedImage.TYPE_INT_RGB); Graphics2D g = bi.createGraphics(); g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,RenderingHints.VALUE_INTERPOLATION_BICUBIC); g.drawImage(thumb, 0, 0,thumbWidth,thumbHeight, null); ByteArrayOutputStream out1 = new ByteArrayOutputStream(); JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out1); JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi); param.setQuality((float)(75/100.0), true); encoder.encode(bi, param); byte[] buf = out1.toByteArray(); String thumbImagePath = "D:\\thumbImages\\"; FileOutputStream os = new FileOutputStream(new File(thumbImagePath+fileName+".jpg")); os.write(buf); } catch(IOException ioException){ ioException.printStackTrace(); } } }

I need it to run it on jre1.5
Please help me


Thanks in advance..

class Super
{
Super()
{
System.out.println("Constructor for Super class");
}

}

public class Sub extends Super
{
Sub()
{
System.out.println("Constructor for Sub class");
}
public static void main(String[] args)
{
Sub subObj=(Sub)new Super();
}
}

Hi,
The above program(Sub.java) is compiling but while running it is giving ClassCastException.. Why???
