import java.util.Locale;

public class MyStringFormatter {

    public static void main(String a[]){
    
        String str = "This is %s format example";
        System.out.println(String.format(str, "string"));
        String str1 = "We are displaying no %d";
        System.out.println(String.format(str1, 10));
        /**
         * String format by specifying Locale details
         */
        System.out.println("String format with Locale info:");
        System.out.println(String.format(Locale.US, str1, 10));
    }
}
