DataInputStream과 DataOutputStream

자바의 기본 데이터 타입을 Stream에 직접 기록이 가능

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

public class DataInputOutputTest {

public static void main(String[] args) throws Exception{

char c = 'A';

char c1 = 'x';

String str = "study";

String str1 = "java";

String file = "C:/Users/sharkmino/Desktop/Music_2.txt";

DataInputStream in = null;

out.writeChar(c);

out.writeUTF(str);

out.close();
