I hope this will guide you to what you want. You need to do something similar to following steps:

  • Read the image,

  • extract RGB values,

  • create another image with ARGB

    BufferedImage bi = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);

  • And apply the operation similar to Image Thresholding to check the white background on image bi, If current pixel is white -> make that pixel transparant. Otherwise(for text image of other color) copy the pixel as it is.

  • And finally save bi as PNG image using

    ImageIO.write(bi, "PNG", new File("C:\yourImageName.PNG"));

Do some research.
