In Java, printf is exactly like string.format, but it does not return anything, it only prints the result. We are going to see how","copyrightYear":"2014","articleSection":"String","articleBody":"\nIn this post, we feature a comprehensive String.format Java Example. In Java, printf is exactly like string.format, but it does not return anything, it only prints the result.\n\n\n\nWe are going to see how to format Strings in Java. Developers familiar with C, will find the methods used here resembling printf function. And the formatting specifications are very similar. In fact, PrintStream class in Java, has a member function called printf designed to work similarly with C's printf.\n\n\n\nYou can also check the Printf Java Example in the following video: \n\n\n\nPrintf Java Example - Video\n\n\n\nLet's see a simple String.format Java example and how you can use it.\n\n\n\n1. Using printf\n\n\n\n\n\n\n\nAs we mentioned in the beginning, in Java, printf is exactly like string.format, but it does not return anything, it only prints the result. The complete signature of printf is printf(String format, Object... args). The first argument is a String that describes the desired formatting of the output. From there on, printf can have multiple number of arguments of any type. At runtime, these arguments will be converted to String and will be printed according to the formatting instructions.\n\n\n\nThe most basic rule that string formatting follows is this:\n\n\n\n\"%[Parameter field][Flags field][Width field][.Precision field][Length field][Type field]\"\n\n\n\n\nSo let's see what all of the above mean :\n\n\n\n\n% is a special character denoting that a formatting instruction follows.\n\n\n\n[Parameter field] or [argument_index$] explicitly denoted the index of the arguments to be formatted. If it not present, arguments will be formatted in the same order as they appear in the arguments list. ($ indicates there is an argument index)\n\n\n\n[Flags field] is a special formatting instruction. For example, the + flag specifies that a numeric value should always be formatted with a sign, and the 0 flag specifies that 0 is the padding character. Other flags include \u2013 that is pad on the right, + pad on the left (if the formatted object is a string) and # is for alternative format. (Note that some flags cannot be combined with certain other flags or with certain formatted objects)\n\n\n\n[Width field] denotes the minimum number of output characters for that Object.\n\n\n\n[.Precision field] denotes the precision of floating point numbers in the output. That is basically the number of decimal digits you wish to print on the output. But it can be used for other types to truncate the output width.\n\n\n\n[Length field]:hh - Convert a variable of type char to integer and printh - Convert a variable of type short to integer and printl - For integers, a variable of type long is expected.ll - For integers, a variable of type long long is expected.L - For floating point, a variable of type long double is expected.z - or integers, an argument is expected of type size_t.\n\n\n\n[Type field] type along with %, are the only mandatory formatting arguments. type simply denotes the type of the object that will be formatted in the output. For integers that is d, for strings that is s, for floating point numbers that is f, for integers with hex format that is x.\n\n\n\n\nLet's see a basic example.\n\n\n\nStringFormatExample.java\n\n\n\n\n\n\n\n\n\n01\n02\n03\n04\n05\n06\n07\n08\n09\n10\n11\n12\n13\n\n\n\npackage com.javacodegeeks.core.string;\n \npublic class StringFormatExample {\n \n    public static void main(String[] args) {\n \n        System.out.printf(\"Integer : %d\\n\",15);\n        System.out.printf(\"Floating point number with 3 decimal digits: %.3f\\n\",1.21312939123);\n        System.out.printf(\"Floating point number with 8 decimal digits: %.8f\\n\",1.21312939123);\n \n        System.out.printf(\"String: %s, integer: %d, float: %.6f\", \"Hello World\",89,9.231435);\n    }\n}\n\n\n\n\n\n\n\n\n\n\nOutput\n\n\n\nInteger : 15\nFloating point number with 3 decimal digits: 1.213\nFloating point number with 8 decimal digits: 1.21312939\nString: Hello World, integer: 89, float: 9.231435\n\n\n\nThe following example depicts the usage of '%b' which will print true if the argument is non null, otherwise prints false.\n\n\n\nStringFormatExample2.java:\n\n\n\npublic class StringFormatExample2{\n\n   public static void main(String[] args){\n\n       System.out.printf(\"%b\\n\",\"Java Code Geeks\");\n\n       System.out.printf(\"%b\\n\",25);\n\n       System.out.printf(\"%b\\n\",null);\n\n   }\n\n}\n\n\n\n\nOutput\n\n\n\ntrue\ntrue\nfalse\n\n\n\n\nThe following example depicts the usage of '%c' which will print the char value of ASCII code provided in the argument.\n\n\n\nStringFormatExample3.java:\n\n\n\npublic class StringFormatExample3 {\n\t\n\tpublic static void main(String[] args){\n\t\t\n\t\tSystem.out.printf(\"%c\\n\", 74);\n\t\t\n\t\tSystem.out.printf(\"%c\\n\", 65);\n\t\t\n\t\tSystem.out.printf(\"%c\\n\", 86);\n\t\t\n\t\tSystem.out.printf(\"%c\\n\", 65);\n\t\t\n\t}\n\n}\n\n\n\n\n\nOutput\n\n\n\n \nJ\nA\nV\nA\n\n\n\n\nThe following example depicts the usage of '%h' which prints the hashcode value of the argument.\n\n\n\nStringFormatExample4.java:\n\n\n\npublic class StringFormatExample4 {\n\t\n\tpublic static void main(String[] args){\n\t\t\n\t\tSystem.out.printf(\"%h\", \"Java Code Geeks\");\t\t\n\t\t\n\t}\n\n}\n\n\n\n\nOutput\n\n\n\nec23cb9a\n\n\n\n\nThe following example depicts the usage of '%o' which prints the Octal value of the argument.\n\n\n\nStringFormatExample5.java:\n\n\n\npublic class StringFormatExample5 {\n\t\n\tpublic static void main(String[] args){\n\t\t\n\t\tSystem.out.printf(\"%o\\n\",25);\n\t\t\n\t\tSystem.out.printf(\"%o\\n\", 100);\n\t\t\n\t}\n\n}\n\n\n\n\nOutput\n\n\n\n31\n144\n\n\n\n\n The following example depicts the usage of '%x' which prints the Hex value of the argument. \n\n\n\nStringFormatExample6.java:\n\n\n\npublic class StringFormatExample6 {\n\t\n\tpublic static void main(String[] args){\n\t\t\n\t\tSystem.out.printf(\"%x\\n\", 25);\n\t\t\n\t\tSystem.out.printf(\"%x\\n\", 100);\t\n\t\t\n\t}\n\n}\n\n\n\n\nOutput\n\n\n\n19\n64\n\n\n\n\nSo let's see some basic rules around string formatting.\n\n\n\nSpecifierApplies toOutput%afloating point (except BigDecimal)Hex output of floating point number%bAny type\u201ctrue\u201d if non-null, \u201cfalse\u201d if null%ccharacterUnicode character%dinteger (incl. byte, short, int, long, bigint)Decimal Integer%efloating pointdecimal number in scientific notation%ffloating pointdecimal number%gfloating pointdecimal number, possibly in scientific notation depending on the precision and value.%hany typeHex String of value from hashCode() method. %nnonePlatform-specific line separator.%ointeger (incl. byte, short, int, long, bigint)Octal number%sany typeString value%tDate\/Time (incl. long, Calendar, Date and TemporalAccessor)%t is the prefix for Date\/Time conversions.%xinteger (incl. byte, short, int, long, bigint)Hex string.\n\n\n\n2.

Using String.format Java\n\n\n\nIf you don't want to print out the String and just want to format it for later use, you can use the static format method of the String class (sort of like sprintf in C). It works in exactly the same way as printf as far as formatting is concerned, but it doesn't print the String, it returns a new formatted String.\n\n\n\nLet's see an example:\n\n\n\nStringFormatExample.java:\n\n\n\n\n\n\n\n\n\n01\n02\n03\n04\n05\n06\n07\n08\n09\n10\n11\n\n\n\npackage com.javacodegeeks.core.string;\n \npublic class StringFormatExample {\n \n    public static void main(String[] args) {\n         \n        String s = String.format(\"%-12.5f%.20f\", 12.23429837482,9.10212023134);\n         \n        System.out.println(s);\n    }\n}\n\n\n\n\n\n\n\n\n\n\nThe above program will print out :\n\n\n\n12.23430    9.10212023134000000000\n\n\n\n The following example depicts the usage of String.format( ) method which stores the formatted String in a variable.\n\n\n\nStringFormatExample14.java:\n\n\n\npublic class StringFormatExample14 {\n\t\n\tpublic static void main(String[] args){\n\t\t\n\t\tlong k = 25000;\n\t\t\n\t\tString italian = String.format(Locale.ITALY,\"%,d %n\", k);\n\t\t\n\t\tString french = String.format(Locale.FRANCE,\"%,d %n\", k);\n\t\t\n\t\tString english = String.format(Locale.ENGLISH,\"%,d %n\", k);\n\t\t\n\t\tSystem.out.print(italian);\n\t\t\n\t\tSystem.out.print(french);\n\t\t\n\t\tSystem.out.print(english);\t\t\t\n\t\t\n\t}\n\n}\n\n\n\n\nOutput\n\n\n\n25.000 \n25 000 \n25,000 \n\n\n\n\n4.
