Can we have images as values in properties file?

I wanted to know can we have images as a values in properties file if so in which folder it needs to be place开发者_JAVA技巧d. Any solutin with example is of great help else point me to some useful solution.

Yes, you can have an image encoded as a base 64 string such as:

You can then decode it for example to a file with:

Base64 decoder = new Base64();   
byte[] imageData = decoder.decode(encodedData);  
FileOutputStream out = new FileOutputStream(new File("trollface.png"););  
out.write(imageData);  
out.close();

The Base64 class is part of the Apache Commons Library.

I don't know what your exact requirements for your applications are, but in the Java Tutorial you can find out about Loading Images using getResource.

You can have any string as the value in a properties file (although a few characters will need to be escaped). There is nothing preventing you from having an image filename (with complete or relative path) as this value.

Note that if you are using windows paths, that backslashes \ need to be escaped (so \\ for each path segment separator).

You can of course not have the actual image itself as the value without some tricky encoding of it to readable characters.
