![]() The latter one requires many arguments which are the same. ‘H’, ‘M’, ‘S’ - Hours, Minutes, Seconds ‘L’, ‘N’ – to represent the time in milliseconds and nanoseconds accordingly ‘p’ – AM/PM ‘z’ – prints out the difference from GMT. Uppercase: jshell> ("%s %S!%n","Hello","World") īoolean formatting examples are given below: jshell> ("%b%n", false) Let’s look at String formatting with a few basic examples: jshell> ("%s %s!%n","Hello","World") Using Comma and Locale: jshell> (Locale.US, "%,d %n", 5000) The following code, aligns to the left: jshell> ("'%-10.2f'%n", 2.28) Filling with zeros Empty spaces to the left of the first character can be filled with zeroes as shown below: jshell> ("'.2f'%n", 2.28) In this section, we’ll see three examples for each of these: jshell> ("'%5.2f'%n", 2.28) Īs you can see the width specifier allocates 5 characters width. Width Specifier, Aligning, Fill With Zeros Precision formatting upto 2 decimal places 3.15Īs you can see it rounds off to the next decimal in the second case. Jshell> ("Precision formatting upto 2 decimal places %.2f\n",z) Precision formatting upto 4 decimal places 2.2800 Jshell> ("Precision formatting upto 4 decimal places %.4f\n",y) Let’s use some precision formatting: jshell> float y = 2.28f Jshell> ("Formatted output is: %d %d%n", x, -x) Here’s an example: | Welcome to JShell - Version 12.0.1 Next, fire up your Jshell and start using printf()! Number Formatting Let’s look at the full syntax of format specifiers with the extended set: %specifierįlags can be set as for right-aligning, and - for left-aligning. \f next line first character starts to the right of current line last character.Escape Charactersįollowing are the escape characters available in printf(): ![]() Note: %n or \n are used as line separators in printf(). Let’s look at the available format specifiers available for printf: printf() uses the class to parse the format string and generate the output.() also prints a formatted string to the console. String.format() returns a formatted string. ![]() Difference between String.format() and () The first one does not do any formatting though and it’s like the println() method.
