escaping - How can I make Java print quotes, like "Hello"?

Question

How can I make Java print "Hello"?

When I type System.out.print("Hello"); the output will be Hello. What I am looking for is "Hello" with the quotes("").

Answer 1

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

The double quote character has to be escaped with a backslash in a Java string literal. Other characters that need special treatment include:

• Carriage return and newline: " " and " "
• Backslash: ""
• Single quote: "'"
• Horizontal tab and form feed: "" and "f"

The complete list of Java string and character literal escapes may be found in the section 3.10.6 of the JLS.

It is also worth noting that you can include arbitrary Unicode characters in your source code using Unicode escape sequences of the form "uxxxx" where the "x"s are hexadecimal digits. However, these are different from ordinary string and character escapes in that you can use them anywhere in a Java program ... not just in string and character literals; see JLS sections 3.1, 3.2 and 3.3 for a details on the use of Unicode in Java source code.
