Logging libraries

You could use logging libraries instead of re-inventing the wheel. Log4j for instance will provide methods for different messages like info(), warn() and error().

Homemade methods

or simply make a println method of your own and call it:

void println(Object line) {
    System.out.println(line);
}

println("Hello World");

IDE keyboard shortcuts

IntelliJ IDEA and NetBeans:

you type sout then press TAB, and it types System.out.println() for you, with the cursor in the right place.

Eclipse:

Type syso then press CTRL + SPACE.

Java is a verbose language   If you are only 3 days in  and this is already bothering you  maybe you d be better off learning a different language like Scala   scala gt  println  Hello World   Hello World   In a loose sense  this would qualify as using a  library  to enable shorter expressions

Using System out println   is bad practice  better use logging framework  -  you should not have many occurences in your code base  Using another method to simply shorten it does not seem a good option
