How Do I Format Strings in Java Using `String.format` and `System.out.printf`?

Formatting Strings in Java

Formatting strings in Java can be achieved using the String.format method. While it resembles the printf family of functions in C, it employs different format specifiers.

To format a string like "Step {1} of {2}", use the following syntax:

String.format("Step %s of %s", "1", "2");

Commonly used format specifiers include:

• %s: Insert a string
• %d: Insert a signed integer
• %f: Insert a real number in standard notation

Unlike C#, which uses positional references with optional format specifiers, Java does not support inserting parameters at different positions.

For direct printing, you can use System.out.printf (or PrintStream.printf), which prints the formatted string output to the specified print stream.
