String.formatted()

Uses the string itself as a template and fills it in — a shorter form of String.format().

Available since: Java 15

Syntax

public String formatted(Object... args)

Parameter	Type	Description
args	Object...	The values to insert, in order.

StringThe formatted string.

Same as String.format(), but called on the template:

void main() {
    String line = "%s: %d points".formatted("Oleg", 42);
    IO.println(line);
}

Output:

Oleg: 42 points

Handy with text blocks:

void main() {
    String card = """
        Name:  %s
        Items: %d
        """.formatted("Anna", 3);
    IO.print(card);
}

Output:

Name:  Anna
Items: 3

The placeholders are the same as in String.format(). As there, the decimal format depends on the system language.

Text blocks and formatting — Multi-line text blocks in Java, formatting strings with formatted, String.format and printf, the %s, %d and %f specifiers and field width.
