Scripting in Java Tutorial - Scripting in Java String

String type represents sequences of Unicode characters.

A sequence of characters enclosed in double quotes or single quotes is a string literal.

The number of characters is the length of the string.

String literals

The following are examples of using string literals:

          
var greetings = "Hi there";      
var title = 'Java Tutorial'; 
var emptyMsg = "";

A string literal can contain single quotes if it is enclosed in double quotes and vice versa.

And we can escape the double quote using a backslash.

var msg1 = "It's Monday.";
var msg2 = 'He said, "Today is Monday."';

var msg3 = 'It\'s Monday.';
var msg4 = "He said, \"Today is Monday.\"";

A string literal in Nashorn can be written in mutiple lines. Use a backslash at the end of the line as the continuation character.

The backslash and the line terminator are not part of the string literal.

The following code has a string in three lines:

var msg = "Hello \
world\
!";

print(msg);

To insert a newline character, use the escape sequence \n.

var msg= "\
Line one\n\
Line two\n\
Line Three\n\
Line Four\
";

print(msg);

The following table lists the escape sequences defined in Nashorn.
