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.
