Figure 104. String literal

Code	Result
String claim = "This is kind of important"; IO.println( claim);	This is kind of important

exercise No. 29

Complete the following code so that the output is being created.

Code	Result
String claim = ...; IO.println( claim);	This is "kind of" important

The two quotes interfere with the outer string delimiters. Java offers a way »escaping« the quote character's syntactical meaning.

Prefixing a backslash solves the issue:

String claim = "This is \"kind of\" important";

IO.println( claim);

Figure 105. Multi line String literal (Java 15)

Code	Result	Code
IO.println("to be is to do (Sokrates)"); IO.println("to do is to be (Sartre)"); IO.println("do be do be do (Sinatra)");	to be is to do (Sokrates) to do is to be (Sartre) do be do be do (Sinatra)	IO.println(""" to be is to do (Sokrates) to do is to be (Sartre) do be do be do (Sinatra)""");

Code

Result

Code

IO.println("to be is to do (Sokrates)");
IO.println("to do is to be (Sartre)");
IO.println("do be do be do (Sinatra)");

to be is to do (Sokrates)
to do is to be (Sartre)
do be do be do (Sinatra)

IO.println("""
   to be is to do (Sokrates)
   to do is to be (Sartre)
   do be do be do (Sinatra)""");

Q:	Use a multi line approach for solving Quote inside strings differently. Tip A multi line string is being delimited by three successive quotes `"""` rather than just one. This offers new chances!
A:	Inside a multi-line string only a groups of three quotes in immediate succession are being prohibited. Thus single quotes no longer pose problems: IO.println(""" This is "kind of" important""");
