            xiaomi.setData("Xiaomi",5.5,3,32,2.6,8.0);
        }
    }

Answer 1

您已通过无效参数。您可以修复发送参数，例如：

xiaomi.setData("Xiaomi",5.5f,3,32,2,8.0f);

或将您的功能签名更改为

String brand,float screensize,int ram,int memory,double processor,float androidversion

并将变量更改为 私人浮动屏幕;

private float androidversion;
private int ram;
private int memory;
private double processor;
private String brand;
