Identifying searchable/non searchable file in java
<p>In my application, i will receive a file. I have to check whether the file has searchable text(text content) or non searchable text(images) and display.</p>

<p>I cannot go with the file extension, because in PDF files, we can have non searchable types also.</p>

<p>I need java code for this. Can anyone help me please.</p>
