Formatting Data - Beginning Java 8 Fundamentals - page 484

SimpleDateFormat sdf = new SimpleDateFormat(pattern);

// Parse the text into a Date object
Date dt = sdf.parse(input, new ParsePosition(0));
System.out.println(dt);

// Get the Calendar instance
Calendar cal = Calendar.getInstance();

// Set the time
cal.setTime(dt);

// Print time parts
System.out.println("Hour:" + cal.get(Calendar.HOUR));
System.out.println("Minute:" + cal.get(Calendar.MINUTE));
System.out.println("Second:" + cal.get(Calendar.SECOND));
System.out.println("Millisecond:" +
cal.get(Calendar.MILLISECOND));

}

Formatting Numbers
In this section, I will discuss how to format numbers. I will also discuss how to parse a string to create a Number object.
The following two classes can be used to format and parse numbers:

java.text.NumberFormat •

java.text.DecimalFormat
The NumberFormat class is used to format a number in a particular locale's predefined format. The DecimalFormat
class is used to format a number in a format of your choice in a particular locale. You can use a getXXXInstance()
method of the NumberFormat class to get the instance of a formatter object, where Xxx can be replaced by Number ,
Currency , Integer , or Percent, or just getInstance() . These methods are overloaded. If you call them without any
argument, they return a formatter object for the default locale. Call the format() method, passing the number as an
argument to get the formatted number as a string.

NumberFormat formatter;

// Get number formatter for default locale
formatter = NumberFormatter.getNumberInstance();
