What is %- 15s in Java?
"%-15s" means that within 15 blank space, the String "s1" will be filled in the left. (fill in the blanks from the left) "%03d" means that within 3 0s, the integer"x" will be filled in the right. (fill in the zeros from the right). This can only be done by using printf method.
It means when % is encountered, the next character determines how to interpret the argument and insert it into the printed result. %s means interpret as string, %d is for digit, %x is digit in hexadecimal, %f is for float, etc.

A printf format reference page (cheat sheet)

By Alvin Alexander. Last updated: Oct 14, 2014

Summary: This page is a printf formatting cheat sheet. I originally created this cheat sheet for my own purposes, and then thought I would share it here. A cool thing about the printf formatting syntax is that the specifiers you can use are very similar, if not identical, between several different languages, including C, C++, Java, Perl, Ruby, Scala, and others, so your knowledge is reusable, which is a good thing. printf formatting with Perl and Java In this cheat sheet I"m going to show all the examples using Perl, but at first it might help to see one example using both Perl and Java. So, here"s a simple Perl printf example to get us started: printf("the %s jumped over the %s, %d times", "cow", "moon", 2); And here are three different Java printf examples, using different methods that are available to you in the Java programming language: System.out.format("the %s jumped over the %s, %d times", "cow", "moon", 2); System.err.format("the %s jumped over the %s, %d times", "cow", "moon", 2); String result = String.format("the %s jumped over the %s, %d times", "cow", "moon", 2); As you can see in that last String.format example, that line of code doesn"t print any output, while the first line prints to standard output, and the second line prints to standard error. In the remainder of this document I"m going to use Perl examples, but again, the actual format specifier strings can be used in many different languages. printf format specifiers - summary Here"s a quick summary of the available printf format specifiers: %c character %d decimal (integer) number (base 10) %e exponential floating-point number %f floating-point number %i integer (base 10) %o octal number (base 8) %s a string of characters %u unsigned decimal (integer) number %x number in hexadecimal (base 16) %% print a percent sign \% print a percent sign

Controlling printf integer width

The "%3d" specifier means a minimum width of three spaces, which, by default, will be right- justified. (Note: the alignment is not currently being displayed properly here.) printf("%3d", 0); 0 printf("%3d", 123456789); 123456789 printf("%3d", -10); -10 printf("%3d", -123456789); -123456789

Left-justifying printf integer output

To left-justify those previous printf examples, just add a minus sign (-) after the % symbol, like this: printf("%-3d", 0); 0 printf("%-3d", 123456789); 123456789 printf("%-3d", -10); -10 printf("%-3d", -123456789); -123456789

The printf zero-fill option

To zero-fill your printf integer output, just add a zero (0) after the % symbol, like this: printf("%03d", 0); 000 printf("%03d", 1); 001 printf("%03d", 123456789); 123456789 printf("%03d", -10); -10 printf("%03d", -123456789); -123456789 printf integer formatting Here is a collection of printf examples for integer printing. Several different options are shown, including a minimum width specification, left-justified, zero-filled, and also a plus sign for positive numbers.

Description Code Result

At least five wide printf(""%5d"", 10); " 10"

At least five-wide, left-justified printf(""%-5d"", 10); "10 " At least five-wide, zero-filled printf(""%05d"", 10); "00010" At least five-wide, with a plus sign printf(""%+5d"", 10); " +10" Five-wide, plus sign, left-justified printf(""%-+5d"", 10); "+10 " printf - floating point numbers Here are several examples showing how to print floating-point numbers with printf.

Description Code Result

Print one position after the decimal printf(""%.1f"", 10.3456); "10.3" Two positions after the decimal printf(""%.2f"", 10.3456); "10.35"

Eight-wide, two positions after the

decimal printf(""%8.2f"", 10.3456); " 10.35"

Eight-wide, four positions after the

decimal printf(""%8.4f"", 10.3456); " 10.3456"

Eight-wide, two positions after the

decimal, zero-filled printf(""%08.2f"",

10.3456); "00010.35"

Eight-wide, two positions after the

decimal, left-justified printf(""%-8.2f"",

10.3456); "10.35 "

Printing a much larger number with

that same format printf(""%-8.2f"",

101234567.3456); "101234567.35"

printf string formatting Here are several printf formatting examples that show how to format string output with printf format specifiers.

Description Code Result

A simple string printf(""%s"", "Hello"); "Hello"

A string with a minimum length printf(""%10s"", "Hello"); " Hello" Minimum length, left-justified printf(""%-10s"", "Hello"); "Hello "

Summary of special printf characters

The following character sequences have a special meaning when used as printf format specifiers: \a audible alert \b backspace \f form feed \n newline, or linefeed \r carriage return \t tab \v vertical tab \\ backslash As you can see from that last example, because the backslash character itself is treated specially, you have to print two backslash characters in a row to get one backslash character to appear in your output. Here are a few examples of how to use this special characters:

Description Code Result

Insert a tab character in a string printf("Hello\tworld"); Hello world Insert a newline character in a string printf("Hello\nworld"); Hello world Typical use of the newline character printf("Hello world\n"); Hello world
