java - java中strtol的等价语句

Question

如何将下面的 objective-c 语句写入 java

unsigned char whole_byte;
char byte_chars[3] = {'\0','\0','\0'};
byte_chars[0] = ....;
byte_chars[1] = [....;
whole_byte = strtol(byte_chars, NULL, 16);

Answer 1

如果变量中有这两个字符。

char ch0 = 'A';
char ch1 = '9';

转换成十六进制数你可以做

int num = Integer.parseInt("" + ch0 + ch1, 16);
