*/publicvoidset(Tvalue){Thread t=Thread.currentThread();ThreadLocalMap map=getMap(t);if(map!=null)map.set(this,value);elsecreateMap(t,value);} 在这个方法内部我们看到,首先通过getMap(Thread t)方法获取一个和当前线程相关的ThreadLocalMap,然后将变量的值设置到这个ThreadLocalMap对象中,当然如果获取...

new is used to create object instances. new takes a single parameter, <class>, the name of the class of object you want to create. <class> is resolved into a Java class (see Chapter 7 for a discussion of how classes are resolved). Then new determines the size in bytes of instances ...

String[] strings= m.create(String.class); } } 代码片段七展示了对泛型数组的擦除补偿,本质方法还是通过显示地传递类型标签,通过Array.newInstance(type, size)来生成数组,同时也是最为推荐的在泛型内部生成数组的方法。 以上,泛型的第二部分的结束。
