java创建线程的方法
方式1：继承Java.lang.Thread类，并覆盖run()方法。优势：编写简单；劣势：单继承的限制----无法继承其它父类，同时不能实现资源共享。方式2：实现Java.lang.Runnable接口，并实现run()方法。优势：可继承其它类，多线程可共享同一个Thread对象；劣势：编程方式稍微复杂，如需访问当前线程，需调用Thread.currentThread()方法。绛旓細鏂瑰紡涓锛氶氳繃缁ф壙Thread绫诲垱寤虹嚎绋婮ava涓殑绾跨▼绫绘槸Thread绫锛屾垜浠彲浠ラ氳繃缁ф壙Thread绫诲垱寤轰竴涓柊鐨勭嚎绋嬨備笅闈㈡槸涓涓娇鐢ㄨ繖绉嶆柟娉曞垱寤虹嚎绋嬬殑绀轰緥浠ｇ爜锛歚publicclassMyThreadextendsThread{publicvoidrun(){System.out.println(绾跨▼杩愯涓);}publicstaticvoidmain(String[]args){MyThreadmyThread=newMyThread()...
