><T><E>详解Jdk5.0新特性Generic Types (泛型) 1. 介绍 2.定义简单Java泛型 其实Java的泛型就是创建一个用类型作为参数的类。就象我们写类的方法一样,方法是这样的method(String str1,String str2 ),方法中参数str1、str2的值是可变的。而泛型也是一样的,这样写class Java_Generics<K,V>,这里边的K和V...

Therefore, the parameter types of OrderedPair's constructor are String and Integer, respectively. Due to autoboxing, it is valid to pass a String and an int to the class. As mentioned in The Diamond, because a Java compiler can infer the K and V types from the declaration OrderedPair<...

As with classes, the main thing to remember is that while the dynamic runtime typing of objects is ignorant of generic typing, the type arguments to statically declared types can be discovered through reflection. Hopefully, Java 7 can "erase erasure", and get rid of this frustrating ...
