Q. Java: What's a nice way to make a heading in the Markdown language?
A. I like this:
void putHeading(final String txt) {
System.out.println(txt);
System.out.println(txt.replaceAll(".","="));
}
void putSubHeading(final String txt) {
System.out.println(txt);
System.out.println(txt.replaceAll(".","-"));
}
This works by turning every character in the heading to an equals (=).
It uses the regular expression dot (.) which matches every character.
The original string is not damaged.
