Formatted output in Java
Sometimes in Competitive programming, it is essential to print the output in a given specified format. Most users are familiar with printf function in C. Let us discuss how we can format the output in Java:
Formatting output using System.out.printf()
This is the easiest of all methods as this is similar to printf in C. Note that System.out.print() and System.out.println() take a single argument, but printf() may take multiple arguments.
Printing simple integer: x = 100 Formatted with precison: PI = 3.14 Formatted to specific width: n = 5.2000 Formatted to right margin: n = 2324435.2500
System.out.format() is equivalent to printf() and can also be used.
Formatting using DecimalFormat class:
DecimalFormat is used to format decimal numbers.
Without fraction part: num = 123 Formatted to Give precison: num = 123.46 appended zeroes to right: num = 123.456700 formatting Numeric part : num = 00123.46 your Formatted Dream Income : $23,456.79
Formatting dates and parsing using SimpleDateFormat class:
This class is present in java.text package.
Formatted Date : 09-08-2018 Parsed Date : Sat Feb 18 00:00:00 UTC 1995
