@文心快码java convert char to int 文心快码 在Java中,将char类型转换为int类型主要有以下几种方法: 1. 直接类型转换 Java允许将char类型直接赋值给int类型变量,此时char值会被自动转换为对应的Unicode码点(通常是ASCII码值,对于ASCII字符而言)。 java char myChar = 'a'; int asciiValue = myChar; // ...

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...
