The getNumberFormat() method of DateFormat class will return an instance of NumberFormat for this DateFormat instance.

Syntax:

public static final NumberFormat getNumberFormat()

Parameter: This method won’t require any parameter.

Return value: This method will return the number formatter which this date/time formatter uses.

The examples given below will illustrate the getNumberFormat() method.

Example 1:

Java




// Java program to illustrate
// getNumberFormat() method
  
// importing the required packages
import java.text.DateFormat;
import java.text.NumberFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
  
class Testclass {
    public static void main(String[] args)
    {
  
        // initializing the DateFormat
        DateFormat df = DateFormat.getDateInstance();
  
        // extracting the year using SimpleDateFormat
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy");
  
        // initializing the NumberFormat
        NumberFormat nf = df.getNumberFormat();
  
        // printing the NumberFormat return value as object
        System.out.println("NumberFormat Object : " + nf);
  
        // formatting the current date into a string
        String str = df.format(new Date());
  
        // printing the current date
        System.out.println("Current date : " + str);
  
        // formatting the current year into a string
        String st = sdf.format(new Date());
  
        // converting the string to integer
        int i = Integer.parseInt(st);
  
        // NumberFormat.format() method
        // accepts only integer and double
        // variables as arguments
  
        // formatting the return value into a string
        String s = nf.format(i);
  
        // printing the formatted value
        System.out.println("Year : " + s);
    }
}
Output
NumberFormat Object : java.text.DecimalFormat@674dc
Current date : Dec 15, 2021
Year : 2021

Example 2 : 

Java




// Java program to illustrate
// getNumberFormat() method
  
// importing the required packages
import java.text.DateFormat;
import java.text.NumberFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
  
class Testclass {
    public static void main(String[] args)
    {
  
        // initializing the DateFormat
        DateFormat df = DateFormat.getTimeInstance();
  
        // extracting the minutes using SimpleDateFormat
        SimpleDateFormat sdf = new SimpleDateFormat("mm");
  
        // initializing the NumberFormat
        NumberFormat nf = df.getNumberFormat();
  
        // printing the NumberFormat return value as object
        System.out.println("NumberFormat Object : " + nf);
  
        // formatting the current time into a string
        String str = df.format(new Date());
  
        // printing the current time
        System.out.println("Current time : " + str);
  
        // formatting the current minutes into a string
        String st = sdf.format(new Date());
  
        // converting the string to integer
        int i = Integer.parseInt(st);
  
        // NumberFormat.format() method
        // accepts only integer and double
        // variables as arguments
  
        // formatting the return value into a string
        String s = nf.format(i);
  
        // printing the formatted value
        System.out.println("Year : " + s);
    }
}
Output
NumberFormat Object : java.text.DecimalFormat@674dc
Current time : 8:35:10 AM
Year : 35
