Use new escape sequences.

Escapes in Text Blocks is a free Java Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Java Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.

New Escapes for Text Blocks

Text blocks support all the usual escapes plus two new ones designed just for them: the line continuation \ and the explicit space \s. These give precise control over output.

Line Continuation with Backslash

Ending a line with \ tells Java not to insert a newline there. The next line joins onto the current one. This lets you wrap long logical lines for readability.

public class Main {
    public static void main(String[] args) {
        String text = """
            This is one \
            single long line.
            """;
        System.out.print(text);
    }
}

Why Line Continuation Helps

You can format source code across several physical lines while producing a single output line. Useful for long sentences or URLs.

public class Main {
    public static void main(String[] args) {
        String url = """
            https://example.com/\
            path/to/\
            resource
            """;
        System.out.print(url);
    }
}

The \s Space Escape

Trailing spaces are normally stripped. The \s escape inserts a literal space that survives stripping, letting you keep meaningful trailing whitespace.

public class Main {
    public static void main(String[] args) {
        String text = """
            red  \s
            green\s
            """;
        for (String line : text.split("\n")) {
            System.out.println("|" + line + "|");
        }
    }
}

Preserving Column Alignment

\s is handy for fixed-width tables where trailing spaces matter for alignment.

public class Main {
    public static void main(String[] args) {
        String table = """
            NAME\s\s\sAGE
            Alice\s\s30
            """;
        System.out.print(table);
    }
}

Standard Escapes Still Work

Classic escapes like \t for tab and \n for newline work inside text blocks too.

public class Main {
    public static void main(String[] args) {
        String text = """
            Col1\tCol2
            A\tB
            """;
        System.out.print(text);
    }
}

Escaping Triple Quotes

To include three consecutive double quotes inside a text block, escape at least one with \" so it is not mistaken for the closing delimiter.

public class Main {
    public static void main(String[] args) {
        String text = """
            He said \"\"\" loudly.
            """;
        System.out.print(text);
    }
}

A Literal Backslash

To put an actual backslash in the output, write \\, exactly as in normal strings. This matters for Windows paths or regex patterns.

public class Main {
    public static void main(String[] args) {
        String path = """
            C:\\Users\\Alice
            """;
        System.out.print(path);
    }
}

Combining Continuation and \s

You can mix both new escapes. Here a continuation joins lines while \s ensures a space at the join point.

public class Main {
    public static void main(String[] args) {
        String sentence = """
            Hello\s\
            World
            """;
        System.out.print(sentence);
    }
}

Avoiding Accidental Newlines

Without continuation, every source line break is a newline. Adding \ at line end removes it, giving you full control of where breaks occur.

public class Main {
    public static void main(String[] args) {
        String joined = """
            part1\
            part2\
            part3
            """;
        System.out.println(joined);
    }
}

Single Quote Needs No Escape

Inside a text block, a single double quote " is fine on its own. Only sequences that could form the closing """ need attention.

public class Main {
    public static void main(String[] args) {
        String quote = """
            She said "hi" to me.
            """;
        System.out.print(quote);
    }
}

Quick Check

What does ending a text block line with a single backslash \ do?

Recap

You learned text block escapes:

\ at line end = line continuation (no newline)
\s = a space that survives trailing-whitespace stripping
Standard \t, \n, \\ still work
Escape a quote to embed """
A lone " needs no escaping
