What is MIME type?

An HTTP response has both header and body. The header info tells the browser about the protocol being used, whether the request is successful and what kind of content is included in the body. The body contains the contents for the browser display.
The “what kind of content” in the header part is known as MIME type.

Some known MIME types:

Type	Meaning
application/vnd.ms-excel	Creates Excel spread sheet
application/msword	Microsoftt word
image/gif	GIF image
image/jpeg	JPEG image
text/plain	Plain text
text/html	HTML document
text/xml	XML document

Example
response.setContentType(“application/vnd.ms-excel”);
PrintWriter out=response.getWriter();
out.println(“\tName \tMath \tPhy \tChem \tTot”);
out.println(“\tAjay \t89 \t70 \t61 \t=sum(B2:D2)”);
out.println(“\tAjay \t83 \t77 \t76 \t=sum(B2:D2)”);
