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
