爪哇 - 声明类和类对象之间的差异和（级VS级）

Question

请参见下面的代码，并说我什么是输精管。

public class c1 
{ 
    //.... 
} 

Class c2 = obj.getClass(); 

Object o1 = new c1(); 
Object o2 = new c2(); // <<----- here 

什么错了最后一行???

我怎样才能创建C2的对象????

编辑：

int[] s1 = new int[]{4,5,6}; 
char[] s2 = new char[]{'a'.'b'}; 

Integer[] new = convertPrimitiveArrayToObject(new Object[]{s1}); 
Character[] new = convertPrimitiveArrayToObject(new Object[]{s2}); 


public static <T> T[] convertPrimitiveArrayToObject(Object[] primitive) 
    { 
      Object x = primitive[0]; 
      Class type = x.getClass().getComponentType(); // => int OR char 
      type[] x2 = (type[]) x;   // I need to convert array to (int/char/...) 

     //...... 
    } 

Answer 1

Object o2 = (C1) c2.newInstance(); 

Answer 2

你需要使用反射，首先阅读Java反射

这将帮助你 Creating New Class Instances

创建对象

Object object = null; 
    try { 
     Class clazz = Class.forName("yor fully qualified class name"); 
     object = clazz.newInstance(); 
    } catch (InstantiationException e) { 
     System.out.println(e); 
    } catch (IllegalAccessException e) { 
     System.out.println(e); 
    } catch (ClassNotFoundException e) { 
     System.out.println(e); 
    }
