ScannerDemo

package day002;
import java.util.Scanner;
public class scanerdemo {
       public static void main(String[] args){
              Scanner sc = new Scanner(System.in);
              System.out.println(sc.nextInt());
              System.out.print(sc.next());
              sc.close();
       }
}

RandomDemo

package day002;

import java.util.Random;



public class RandomDemo {

       public static void main(String[] args){

              getRandInt();

       }

       public static void getRandInt(){

              Random random = new Random();

              System.out.print(random.nextInt(1000));

       }
