java-Cannot reduce the visibility of the inherited method from 父类

public class Practice {

	protect String toString()
	{
		return super.toString();
	}
}

这样写有  java-Cannot reduce the visibility of the inherited method from 父类

原因是子类重写父类方法   权限修饰范围必须大于父类的范围

把修饰符改为public 就对了

public String toString()
	{
		return super.toString();
	}

这样写就对了
