Can you tell me how to increase the size of the font using System.out.println in java.
There is a way to change fonts for Java output. See details here:

There is no concept of "font" with System.out.
Edit the console font settings for whatever application you're using as an output console.
You cannot do this through coding as in the font size is based on your console. I assumed you use eclipse to code your java code. So, you can change eclipse console font size here. General > Appearance > Colors and Fonts
Which you can get the source here. http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftasks-consoleAppearance.htm
This is a console output. Unfortunately there is no way to do it.
