Java 如何使用数组进行减法/除法 //声明并初始化变量-程序员提供初始值 扫描仪输入=新扫描仪（系统输入）； String city=“代托纳海滩”； 字符串state=“佛罗里达”； 双a=0； 字符串月[]={“一月”、“二月”、“三月”、“四月”、“五月”、“六月”、“七月”、“八月”、“九月”、“十月”、“十一月”、“十二月”}； 双温[]={58.4,60.0,64.7,68.9,74.8,79.7,81.7,81.5,79.9,74.0,67.0,60.8}； 双重降水[]={3.1,2.7,3.8,2.5,3.3,5.7,5.2,6.1,6.6,4.5,3.0,2.7}； 字符串tempLabel=“F”//初始化为F 字符串precipLabel=“英寸”//初始化为英寸 双c[]={32.0}； 双q[]={0.5555}； //输入-要求用户选择温度和沉淀刻度 System.out.print（“选择温度刻度（F=华氏度，C=摄氏度）：”； 字符串tempChoice=in.next（）； System.out.print（“选择降水量刻度（i=英寸，c=厘米）：”； 字符串precipChoice=in.next（）； //处理-根据用户的选择从F转换为C，从in转换为cm //记住5/9=0，5.0/9=0.5555 if（tempChoice.equalsIgnoreCase（“C”）） { tempLabel=“（C）”； 对于（int index=0；index

不要担心降水量的换算。如何转换多个数组值（以华氏度为单位）？我试着做（例如）：a[I]=b[I]-c[I]，但总是得到关闭温度阵列的错误。错误应为“']”

**我还收到编译器警告“上一次编译的警告：

• 非varargs调用最后一个参数类型不精确的varargs 周长

• 为varargs调用强制转换为java.lang.Object

• 对于非varargs调用，强制转换为java.lang.Object[]，并抑制 警告
