Почему спецификатор формата %.3f выдает ошибку в Java? ⇐ JAVA

[Anonymous]

So I am trying to print first 3 digits of PI using floating point format specifier in java, using the following code:

public class PrettyPrinting { public static void main(String[] args) { float a = 453.1274f; System.out.printf("Formatted number is %.2f \n", a); System.out.printf("Pi is: %.3f \n" + (float)Math.PI); } } And it is giving me the following Exception stack trace:

Formatted number is 453.13 Pi is: Exception in thread "main" java.util.MissingFormatArgumentException: Format specifier '%.3f' at java.base/java.util.Formatter.format(Formatter.java:2688) at java.base/java.io.PrintStream.format(PrintStream.java:1209) at java.base/java.io.PrintStream.printf(PrintStream.java:1105) at PrettyPrinting.main(PrettyPrinting.java:6) Process finished with exit code 1 I have tried with the format specifier of doble also but the issue still doesn't get resolved and a different stack trace of Exception appears in the console. The error appears even without explicit typecasting.
