[Thread 실습문제]
<문제 1> 
 - 실행용클래스 com.thread.sleep.SleepTest
 + sendAphorism() : void 

 - 좋아하는 속담, 경구 10개를 문자열배열에 담고, 3초마다 랜덤하게 출력하세요.
 - 10번 출력후 종료하세요.

package com.thread.sleep;

public class SleepTest implements Runnable{

	@Override
	public void run() {
		String[] strarr =new String[10];
		
		strarr[0] = "Regret for wasted time is more wasted time";
		strarr[1] = "connecting the dots";
		strarr[2] = "Love yourself.";
		strarr[3] = "Seize the day";

- 쓰레드 클래스 : com.thread.alphabet.UpperAlphbetThread.java
               com.thread.alphabet.LowerAlphbetThread.java    
두개의 멀티쓰레드를 만들고, 각각 알파벳대문자, 알파벳 소문자를 출력하세요.

		Thread th2  = new Thread(new LowerAlphabetThread(),"소문자");
		
		th1.start();
		th2.start();
	}
