The out() method is a built-in method of the java.util.Formatter which returns the destination for the output by the formatter.
Syntax:
public Appendable out()
Parameters: The function accepts no parameter.
Return Value: The function returns the destination for the output.
Exceptions: The function throws FormatterClosedException if the formatter has been closed before the function call.
Below is the implementation of the above function:
Program 1:
// Java program to implement// the above function  import java.util.Formatter;import java.util.Locale;  public class Main {      public static void main(String[] args)    {          // Get the string Buffer        StringBuffer buffer            = new StringBuffer();          // Object creation        Formatter frmt            = new Formatter(buffer,                            Locale.CANADA);          // Format a new string        String name = "My name is Gopal Dave";        frmt.format("What is your name? \n%s !",                    name);          // Print the Formatted string        System.out.println(frmt);          // Prints the destination of the output        System.out.println("\nDestination: "                           + frmt.out());    }} |
Output:
What is your name? My name is Gopal Dave ! Destination: What is your name? My name is Gopal Dave !
Program 2:
// Java program to implement// the above function  import java.util.Formatter;import java.util.Locale;  public class Main {      public static void main(String[] args)    {        try {              // Get the string Buffer            StringBuffer buffer                = new StringBuffer();              // Object creation            Formatter frmt                = new Formatter(buffer,                                Locale.CANADA);              // Format a new string            String name = "My name is Gopal Dave";            frmt.format("What is your name? \n%s !",                        name);              // Print the Formatted string            System.out.println(frmt);              // Formatter closed            frmt.close();              // Prints the destination of the output            System.out.println("\nDestination: "                               + frmt.out());        }        catch (Exception e) {            System.out.println("Exception is: "                               + e);        }    }} |
Output:
What is your name? My name is Gopal Dave ! Exception is: java.util.FormatterClosedException
