3Order

Put the learning moves in the order that makes the concept easiest to apply.

The solution to avoid this problem, is to use the backslash escape character .

Because strings must be written within quotes, Java will misunderstand this string, and generate an error:

Strings - Special Characters

Because strings must be written within quotes, Java will misunderstand this string, and generate an error:

String txt = "We are the so-called "Vikings" from the north.";

String txt = "It\'s alright.";

String txt = "The character \\ is called backslash.";

Other common escape sequences that are valid in Java are:

Note
