java根据字符串获取类名

代码如下

public class Test {
	
	public static void main(String[] args) throws InstantiationException, IllegalAccessException, ClassNotFoundException {
		System.out.println(getclass("com.company.interfacetest.Person").getSimpleName());
	}
	
	public static Class getclass(String className) throws InstantiationException, IllegalAccessException, ClassNotFoundException//className是类名
	{
	   Class obj=Class.forName(className); //以String类型的className实例化类
	   return obj;
	}
}

输出结果

person
