Java STDIO Examples

Here are some STIO examples I found online. If they do not work -- let me know. The first example is a teamm supplied code sample. The others ame from http://www.loirak.com/prog/java.php

    import java.util.*;
    import java.io.*;
   
    public class example {
       public static void main(String[] args){
           Scanner in = new Scanner(System.in);
           int num = in.nextInt();
           for (int i=0; i<num; i++) {
                   String carnum = in.next();
                   String name = in.nextLine();
                   System.out.println(name+" drives car number "+carnum);
           }
       }
   }
    

2. class Hello {
     public static void main (String[] args) {
       System.out.println("Welcome to the world of Java Programming.");
     } // method main
   } // class Hello

3. import java.io.*; //include Java's standard Input and Output routines
   
   class Echo {
     public static void main (String[] args) throws IOException {
   
       // Defines the standard input stream
       BufferedReader stdin = new BufferedReader
         (new InputStreamReader(System.in));
       String message; // Creates a varible called message for input
   
       System.out.print ("Enter the message : ");
       System.out.flush(); // empties buffer, before you input text
       message = stdin.readLine();
   
       System.out.print("You "); 
       System.out.println("entered : " + message);
   
     } // method main
   } // end of class Echo

4. import java.io.*; 
   
   class Candy {
     public static void main (String[] args) throws IOException {
   
       BufferedReader stdin = new BufferedReader
         (new InputStreamReader(System.in));
       int num1, num2, sum; // declares three integers
       double dollars; // declares a number that can have decimals
   
       System.out.print ("How many candy bars do you want  : ");
       System.out.flush(); 
   
       // read a line, and then converts it to an integer
       num1 = Integer.parseInt( stdin.readLine());
   
       System.out.print ("How many suckers you do want  : ");
       System.out.flush(); 
       num2 = Integer.parseInt( stdin.readLine());
   
       sum = num1 + num2; // Adds the two numbers;
       dollars = (double) sum * .75;
       System.out.println("You owe : $" + dollars);
     } // method main
   } 

5. import java.io.*; 
   
   class Loopit {
     public static void main (String[] args) throws IOException {
       BufferedReader stdin = new BufferedReader
         (new InputStreamReader (System.in));
       int count, max, num;
       num = 0; // Assign initial value of count
       while (num != -1) {
         System.out.print ("Enter a number to factorialize (-1 to quit): ");
         System.out.flush();
         num = Integer.parseInt (stdin.readLine());
         max = 1; // Assign to 1, so factorial isn't zero every time
         if (num == -1) { 
           System.out.println("Okay, quiting...");
         }
         else { // Since they're not quitting we better factorialize
           for  (count = 1; count<=num; count++) {
             max = count * max;
           }    
           System.out.println (num+"! (factorial) is : "+ max);
         }
       } 
     } // method main
   }
