Issue
How can I print output in bold in printf? "[1m testing bold" does not do anything.
String format = "%-20s %-15s %-20s %-15s %-10s";
System.out.printf(format, "Name", "Group_name", "Java_Prof_Level", "Cpr_Nr", "Gender", "[1m testing bold");
Solution
You cannot print bold with Java System.out. It just streams to the standard output stream so, in principle, it is unformatted text only.
However, some software packages interpret special character sequences (the so-called ANSI escape sequences) to allow formatting.
Note that ANSI escape sequences start with an escape character, so you need to add that to your string also. (Try "\u001B[1m I am bold" or "\033[0;1m" + "I am bold".)
Most Unix terminals interpret ANSI escape sequences by default. In old DOS times, you needed to use ANSI.SYS for the escape sequences to work.
In Windows and the Eclipse terminal the codes do not work.
