Java 十进制转十六进制（大写）代码示例

public class DecimalToHexadecimal { public static void main(String[] args) { int decimal = 255; String hexadecimal = ""; char[] hexDigits = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'};

    while (decimal > 0) {
        int remainder = decimal % 16;
        hexadecimal = hexDigits[remainder] + hexadecimal;
        decimal /= 16;
    }

    System.out.println(hexadecimal);
}

}
