java string format placeholder

I'd be happy to help you with that!

Java provides various ways to format strings using placeholders. Here are some common ones:

%s: This is the most basic placeholder, used for printing strings.

Example: System.out.printf("Hello, %s!", "World");

Output: "Hello, World!"

%d: Used for printing integers.

Example: System.out.printf("The answer is %d", 42);

Output: "The answer is 42"

%.2f: Used for printing floating-point numbers with two decimal places.

Example: System.out.printf("%.2f", 3.14159);

Output: "3.14"

%b: Used for printing booleans (true or false).

Example: boolean isAdmin = true; System.out.printf("You are %b administrator.", isAdmin);

Output: "You are true administrator."

%%: Escapes the percentage sign, so it's treated as a literal character.

Example: System.out.printf("The escape sequence is %%");

Output: "The escape sequence is %"

%n: Used for printing newline characters (carriage return and line feed).

Example: System.out.printf("Hello!n%nWorld!", "");

Output:

"Hello!

World!"

%t: Used for formatting dates and times.

Example: Date date = new Date(); System.out.printf("%tc", date);

Output: "Sat Nov 27 14:30:00 GMT 2021"

%x: Used for formatting hexadecimal numbers.

Example: int hexValue = 0xFF; System.out.printf("%x", hexValue);

Output: "ff"

%o: Used for formatting octal numbers.

Example: int octValue = 15; System.out.printf("%o", octValue);

Output: "17"

%p: Used for printing platform-dependent values like file paths or directories.

Example: File dir = new File("/path/to/dir"); System.out.printf("%p", dir.getAbsolutePath());

Output: "/path/to/dir"

These are some of the most commonly used placeholders in Java string formatting. You can mix and match them to create complex output strings!
