String name = "Bruce"; Integersare whole numbers. They can be any number from-2147483648to2147483647. Setting an integer is just like setting up a string, the only difference is that you need to use theintkeyword at the beginning, and the value that you are going to store in, doesn’t...
在Java中,将字符串转换为整数的标准方法是使用`Integer.parseInt()`,对应选项A。 - **选项A**:`parseInt()`是`Integer`类的静态方法,接受字符串参数并返回对应的基本类型`int`,正确。 - **选项B**:`toInteger()`不是Java标准库中的方法,`Integer`类中无此方法,错误。 - **选项C**:`toInt()`也不...
1.Convert.ToInt是数据类型转换成int类型 2. 有三种方法toint16,toint32,toint64 int16-数值范围:-32768 到 32767 int32-数值范围:-2,147,483,648 到 2,147,483,647 int64-数值范围:-9223372036854775808 到 9223372036854775808 3.所以,按需使用吧
