Example Of Making a dynamic PROGRAM

Add the following statement at the top of the code
            import java.io.BufferedReader;
            java.io.InputStreamReader import;
            import java.io.IOException;

                import java.io.*;

Numbers input class
            {
                        public static void main (String [] args) throws IOException
            {
Step 1. Declaration of Variable Input / output
            String temp;
            int number;

Step 2. Stat.Input connect with keyboard
            InputStreamReader isr = new InputStreamReader (System.in);
            BufferedReader br = new BufferedReader (new InputStreamReader (System.in));
     Or
            InputStreamReader isr = new InputStreamReader (System.in);
            BufferedReader bil = new BufferedReader (isr);
     Or
            BufferedReader bil = new BufferedReader (new InputStreamReader (System.in));
 
Step 3.Input Data
            System.out.print ("Enter an integer:");

Step 4. Translating the input variables
            / * consider what data will be inputkan, is of type char, string or numeric * /
            / * note also that the data on double-inputkan numeric or integer type * /
                        temp = bil.readLine ();
                        number = Integer.parseInt (temp);

Step 5. output data
            System.out.println ("Numbers are entered" + "is" + number);
            }
            }
