Can Java String Literals Be Written Without Escaping Quotes?

Escaping Quotes in Java Output

When attempting to print a string with double quotes in Java, users may encounter the issue of the quotes being omitted from the output. To address this, it is necessary to escape the double quote character with a backslash.

For instance, the following code will print "Hello" within double quotes:

System.out.print("\"Hello\"");

This technique applies not only to double quotes but also to other special characters that require escaping in Java string literals. Below is a list of these characters:

• Carriage return and newline: "r" and "n"
• Backslash: ""
• Single quote: "'"
• Horizontal tab and form feed: "t" and "f"

For a comprehensive list of Java string and character literal escapes, refer to section 3.10.6 of the Java Language Specification (JLS).

Furthermore, Java supports including arbitrary Unicode characters in the source code using Unicode escape sequences (e.g., "uxxxx"). These sequences can be utilized anywhere in the program and are distinct from ordinary string and character escapes.
