Reflection of an array

First, the array class type

Representation of an array class type: An array object. GetClass array dimension. Class

1 import Java.lang.reflect.Method;2 3  Public classTest {4    Public Static voidMain (string[] args) {5     Try {6Class c=b.class;7Method Method=c.getmethod ("Show",NewClass[]{string[].class,int[].class});8          //The class type object of an array is only related to the array name and the group dimension9          //such as int[] a={1,2,3} int[] b={2,3,4,5} so a.getclass==b.getclass; Description class type Object is the sameTenMethod.invoke (C.newinstance (),Newobject[]{Newstring[]{" as","SD"},New int[]{1,2}} ); One}Catch(Exception e) { A e.printstacktrace (); -     }  -   } the } - classb{ -      Public voidShow (string[] s,int[] r) { -          for(inti:r) { +System. out. println (i); -         } +          for(String t:s) { ASystem. out. println (t); at         } -     } -}

2. Determine if the object being transmitted is an array

 Public void Object {      Class  c=object. getclass;     C.isarray (); // determines if the object being passed is an array }
