// Let's look at a few examples to quickly understand printf function.

System.out.printf("%d", 5);// 5

System.out.printf("My name is %s", "Rithu");// My name is Rithu

System.out.printf("%s is %d Years old", "Rithu", 5);// Rithu is 5 Years

// old

// In the simplest form, string to be formatted starts with % followed

// by conversion indicator

// b - boolean c - char d - integer f - floating point s - string.

// Prints 12 using minimum 5 character spaces.

System.out.printf("|%5d|", 12); // prints | 12|

// Prints 1234 using minimum 5 character spaces.

System.out.printf("|%5d|", 1234); // prints | 1234|

// In above example 5 is called width specifier.

// Left Justification can be done by using -

System.out.printf("|%-5d|", 12); // prints |12 |

// Using 0 pads the number with 0's

System.out.printf("%05d", 12); // prints 00012

// Using , format the number using comma's

System.out.printf("%,d", 12345); // prints 12,345

// Using ( prints negative numbers between ( and )

System.out.printf("%(d", -12345); // prints (12345)

System.out.printf("%(d", 12345); // prints 12345

// Using + prints + or - before the number

System.out.printf("%+d", -12345); // prints -12345

System.out.printf("%+d", 12345); // prints +12345

// For floating point numbers, precision can be specified after.

// Below example uses a precision of 2, so .5678 gets changed to .57

System.out.printf("%5.2f", 1234.5678); // prints 1234.57

// An error in specifying would give a RuntimeException

// In below example a string is passed to %d argument.

// System.out.printf("%5d","Test");

// Throws java.util.IllegalFormatConversionException

// To change the order of printing and passing of arguments, argument

// index can be used

System.out.printf("%3$.1f %2$s %1$d", 123, "Test", 123.4); // prints

// 123.4

// Test 123

// format method has the same behavior as printf method

System.out.format("%5.2f", 1234.5678);// prints 1234.57
