How to package java?

The first one: use System.out.println()// This is a new line.

Second, use system. out.print ("\ n"); //This is another line.

The first one is similar to the second one. It's just, if you want to change two lines, three lines and more lines.

Just use: system. out.println ("\ n \ n"); Change two lines

Three lines: system. out.println ("\ n \ n" \ n);
