mp3 to wav conversion in java

My code to convert mp3 to wav is:

package audio1;

import java.io.File;
import javax.sound.sampled.AudioFileFormat;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;

public class NewClass {
    public static void main(String [] args){
        try{
            AudioFileFormat inputFileFormat = AudioSystem.getAudioFileFormat(new File("c:\\1.mp3"));
            AudioInputStream ais = AudioSystem.getAudioInputStream(new File("c:\\1.mp3"));

            AudioFormat audioFormat = ais.getFormat();

            System.out.println("File Format Type: "+inputFileFormat.getType());
            System.out.println("File Format String: "+inputFileFormat.toString());
            System.out.println("File lenght: "+inputFileFormat.getByteLength());
            System.out.println("Frame length: "+inputFileFormat.getFrameLength());
            System.out.println("Channels: "+audioFormat.getChannels());
            System.out.println("Encoding: "+audioFormat.getEncoding());
            System.out.println("Frame Rate: "+audioFormat.getFrameRate());
            System.out.println("Frame Size: "+audioFormat.getFrameSize());
            System.out.println("Sample Rate: "+audioFormat.getSampleRate());
            System.out.println("Sample size (bits): "+audioFormat.getSampleSizeInBits());
            System.out.println("Big endian: "+audioFormat.isBigEndian());
            System.out.println("Audio Format String: "+audioFormat.toString());

            AudioInputStream encodedASI = AudioSystem.getAudioInputStream(AudioFormat.Encoding.PCM_SIGNED, ais);

            try{
                int i = AudioSystem.write(encodedASI, AudioFileFormat.Type.WAVE, new File("c:\\converted.wav"));
                System.out.println("Bytes Written: "+i);
            }catch(Exception e){
                e.printStackTrace();
            }
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}
