Java对象实例化

　　2、带参数构造方法
public class NewObject
{
String name;
public NewObject()
{
System.out.println(“ the object is created!”);
}
public void write()
{
System.out.println(“”);
}
}
　　使用以下代码可实现实例化：
try
{
no=(NewObject)Class.forName(className).getConstructor(String.class).newInstance(names);
//no=(NewObject)Class.forName(className).getConstructor(newObject[]{String.class}).newInstance(names);
}
catch(IllegalArgumentExceptione)
{
e.printStackTrace();
}
catch(SecurityExceptione)
{
e.printStackTrace();
}
catch(InstantiationExceptione)
{
e.printStackTrace();
}
catch(IllegalAccessExceptione)
{
e.printStackTrace();
}
catch(InvocationTargetExceptione)
{
e.printStackTrace();
}
catch(NoSuchMethodExceptione)
{
e.printStackTrace();
}
catch(ClassNotFoundExceptione)
{
e.printStackTrace();
}
　　3、带数组参数构造方法
　　public class NewObject
　　{
　　String name;
　　public NewObject(String name)
　　{
　　this.name = name;
　　System.out.println(“ the object is created!”);
　　}
　　public void write()
　　{
　　System.out.println(this.name);
　　}
　　}
　　使用以下代码可实现实例化：
try
{
Constructor[] cs;
cs = Class.forName(className).getConstructors();
Constructor cc = Class.forName(className).getConstructor(String[].class);
no = (NewObject)cc.newInstance(new Object[]{names});
}
catch (SecurityException e)
{
e.printStackTrace();
}
catch (ClassNotFoundException e)
{
e.printStackTrace();
}
catch (NoSuchMethodException e)
{
e.printStackTrace();
}
catch (IllegalArgumentException e)
{
e.printStackTrace();
}
catch (InstantiationException e)
{
e.printStackTrace();
}
catch (IllegalAccessException e)
{
e.printStackTrace();
}
catch (InvocationTargetException e)
{
e.printStackTrace();
}
