JAVA泛型方法与类型限定

1 class ArrayAlg{
2     public static <T> T getMiddle(T...a){
3         return a[a.length/2];
4     }
5 }

String middle=ArrayAlg.<String>getMiddle("John","Q.","Public");

String middle=ArrayAlg.getMiddle("John","Q.","Public");

 1 class ArrayAlg{
 2     public static <T> T min(T[] a){
 3         if(a==null||a.length==0) return 0;
 4         T smallest=a[0];
 5         for(int i=1;i<a.length;i++)
 6             if(smallest.compareTo(a[i])>0)
 7                 smallest=a[i];
 8             return smallest;
 9     }
10 }

public static <T extends Comparable> T min(T[] a)...

T extends Comparable & Serializable
