Class.forName("binary name");
加載并對(duì)類變量進(jìn)行初始化
等價(jià)cl.loadClass("binary name").newInstance();

ClassLoader.loadClass("binary name");
ClassLoader cl = this.getClass().getClassLoader();
Class c = cl.loadClass("binary name");
Object obj = c.newInstance();
在newInstance時(shí)初始化
初始化時(shí)會(huì)比forName多產(chǎn)生一個(gè)obj對(duì)象
