使用String.ValueOf()将Float中的Float转换为String显示异常 - java.lang.ClassCastException:java.lang.Float无法强制转换为[C

问题描述 投票:0回答:1

我一直在尝试使用Selenium运行与REST API相关的一些测试。根据下面的代码,我需要将Float值转换为String。

当我使用String.valueOf(float arg)时,我得到了异常 - java.lang.ClassCastException:java.lang.Float无法强制转换为[C

码:

@Test

public void Test01()
{
    Response r=given().parameter("id", "someID").parameter("appid", "someID").when().get("someURL");

    String lon=String.valueOf(r.then().contentType(ContentType.JSON).extract().path("coord.lon"));

    System.out.println(lon);
}

预期:价值转换必须成功。即浮点数 - >字符串

实际:失败:Test01

java.lang.ClassCastException: java.lang.Float cannot be cast to [C

更改代码的这一部分

String lon=String.valueOf(r.then().contentType(ContentType.JSON).extract().path("coord.lon"));

需要使用Float.toString()方法

String lon=Float.toString(r.then().contentType(ContentType.JSON).extract().path("coord.lon"));
