内部类 newinstance failed no init ()

public class TestJsonParase extends AndroidTestCase {

	public class TempClass {
		int c=0 ;
		public TempClass(){
		}
	}
	

	
	public void testJsonToObject(){
		String json = "{a:b,c:1}";
		JSONObject object  = null ;
		try {
			object = new JSONObject(json);
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		Class<?> demo = OldInformation.class;   
        Object obj = null;   
		
        TempClass tempClass = null;
        try {
        	tempClass = TempClass.class.newInstance() ;
		} catch (InstantiationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
        assertNotNull(tempClass);
    }
}

这个为什么会出错呢？tempClass 为空。
