The following sections review again on something, run the following code yourself
public static void main(String[] args) {
//字符类型变量
char c = 'a';
int i = 1;
//字符类型和int类型计算
System.out.println(c+i);//输出结果是98
}
(In the process of char and an int type of calculation, the first query char type character code table, to give 97, and then a sum, the result is to enhance an int type 98.char .char Type 2 bytes of memory, int type 4 bytes of memory.)
Look at the whole ASCII table:
This is the number corresponding ASCII table, the table does not need a lot of content there is one to remember, you only need to remember the common values, as follows:
