    中国大学MOOC: 以下Pair泛型类public class Pair<K, V> { public Pair(K key, V value) { this.key = key; this.value = value; } public K getKey(); { return key; } public V getValue(); { return value; } public void setKey(K key) { this.key = key; } public void setValue(V value) { this.value = value; } private K key; private V value;}经过类型擦除后,变成以下类public class Pair { public Pair(Object key, Object value) { this.key = key; this.value = value; } public Object getKey() { return key; } public Object getValue() { return value; } public void setKey(Object key) { this.key = key; } public void setValue(Object value) { this.value = value; } private Object key; private Object value;}
