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
