[16] Scanner 클래스로 입력

## 기본모양 1 (콘솔모드)##

// Scanner Class : 입력하는 클래스....
import java.io.*;
import java.util.*;

	public static void main(String[] args) throws IOException{
		Scanner in = new Scanner(System.in);
		System.out.print("문자열 =");
		String str = in.next();
		
		System.out.print("숫자 = ");
		int x = in.nextInt();
		
		
		System.out.println(str);
		System.out.println(x);

## 기본모양 2 (파일모드)##
