Thread 기본개념 활용

class SomeThread extends Thread{
	
	private String name;
	
	public SomeThread(String name) {
		this.name = name;
	}
	
	
	public void run() {
		
		for(int x = 0 ; x < 1000 ; x++) {
			System.out.println(name + "] " + x);	
		}
	}
	
}

new SomeThread("안녕").start();
new SomeThread("반가웡").start();
new SomeThread("hello").start();


for(int x = 0 ; x < 1000 ; x++) {
    System.out.println("main] " + x);

// 원래내가하던것: 매서드 run호출
// 위에서부터 순차적으로 실행이 될거야

// 스레드: start매서드로 호출
// 병렬식으로 멋대로 출력이될거고, 순서는 알 수 없다

 

//** synchronized : 순서대로 실행되도록 함

// ex. 여러 페이지를 다운받을때, 하나씩 다운받는게 아니라 주르륵 다운받도록하면 좀 빠르겠지?
