int 根据Java的自动类型转换规则,当操作数类型不同时,Java会将较小的数据类型自动提升为较大的类型。具体情况如下:1. **char与int的关系**: - `char`本质是16位无符号整数(0~65535)。 - `int`是32位有符号整数。 - 当`char`与`int`参与运算时,`char`会被自动提升为`int`。
publicclassMyClass{publicstaticvoidmain(String args[]){charmyChar='5';intmyInt=myChar-'0';System.out.println("Value after conversion to int: "+myInt);}} Output: These are the two commonly used methods to convert acharto anintin Java. However, keep in mind that even if the givenchardo...
