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); } } } |
What is your name? My name is Gopal Dave ! Exception is: java.util.FormatterClosedException
