java中，char类型能不能转换成int类型？能不能转换成string类型？能不能转换成double类型？
1. char类型可以转换成int类型。可以通过强制类型转换实现，例如：`(int) ch;`，其中ch是一个char类型的变量。 2. char类型可以转换成String类型。可以通过Character类的toString()方法或者String类的valueOf()方法实现，例如：`String.valueOf(ch);` 或者 `new String(ch);`。 3. char类型不能直接转换成double类型，但可以先转换成int类型，然后再转换成double类型。例如：`(double) (int) ch;`。 [2023-11-01 15:09:59 | AI小红书种草文 | 116点数解答]
