23. Applying indentation

Starting with JDK 12, we can indent text via the String.indent(int n) method.

Let's assume that we have the following String values:

String days = "Sunday\n"   + "Monday\n"   + "Tuesday\n"   + "Wednesday\n"   + "Thursday\n"   + "Friday\n"   + "Saturday";

Printing this String values with an indentation of 10 spaces can be done as follows:

System.out.print(days.indent(10));

The output will be as follows:

Now, let's try a cascade indentation:

List<String> days = Arrays.asList("Sunday", "Monday", "Tuesday",  "Wednesday", "Thursday", "Friday", "Saturday");for (int i = 0; i < days.size(); i++) { System.out.print(days.get(i).indent(i)); ...
