I have a String like "09a" and I need a method to confirm if the text is hexadecimal. The code I've posted does something similar, it verifies that a string is a decimal number. I want to do the same, but for hexadecimal.

Thank you very, very much!

    private static boolean isNumeric(String cadena) {    try {        Long.parseLong(cadena);        return true;    } catch (NumberFormatException nfe) {        JOptionPane.showMessageDialog(null,"Uno de los números, excede su capacidad.");        return false;    }}

So I have kind of hit a road block in my project.What I am trying to do is figure out a way to take four individual binary characters which are representing flags. Now my last task was to take these four flags and put them in a char[] which wasn't difficult at all. But now, I want to take the four and convert it to a hex.

So for example:

O = 1;C = 1;Z = 0;N = 0;char flags[5];flags[0] = O;flags[1] = C;flags[2] = Z;flags[3] = N;

Now I wanted to make a string or something i can convert the above to a Hex. So for example I want to have 1100 converted to a hex which is 0xC

Now I have tried to make it in to a string first then parse it but I'm confused and lost now. I just can't see to get the right output.

Recently I would like to transfer '@MOVE' to b'\x40\x4d\x4f\x56\x45' using python 3.4.4, however it's easy to get the result: b'\\\\x40\\\\x4d\\\\x4f\\\\x56\\\\x45', the result is not what I want. so my question is how to handle the code to get my wanted answer. thanks!Codes:

str2 = '@MOVE P,P2'print(str2)temp=[]for ea in str2:    m = ord(ea)    temp.append(m)temp1 = []str0=''for ea1 in temp:    n = hex(ea1)    str0 = str0 + "\\" + n[1:]    temp1.append(n)str0 = str0 + '\r'+'\n'print(100*'#')print(str0.encode('ASCII'))

output:

@MOVE P,P2####################################################################################################b'\\\\x40\\\\x4d\\\\x4f\\\\x56\\\\x45\\\\x20\\\\x50\\\\x2c\\\\x50\\\\x32\r\n'

In Windows Forms application I have one text box in which user can write ASCII or HEX string and I want to wimplement a code which will recognise if entered string is ASCII or HEX format.If it is ASCII is need to convert it in HEX. How can I do this ? Any ideas?I also have this code for convert ascii to hex:

Dim str As String = "test"Dim byteArray() As ByteDim hexNumbers As System.Text.StringBuilder = New System.Text.StringBuilderbyteArray = System.Text.ASCIIEncoding.ASCII.GetBytes(str)For i As Integer = 0 To byteArray.Length - 1    hexNumbers.Append(byteArray(i).ToString("x"))NextMsgBox(hexNumbers.ToString()) 

I have a bit-string of 32 characters that I need to represent as hexadecimal in Python. For example, the string "10000011101000011010100010010111" needs to also be output as "83A1A897".

Any suggestions on how to best go about this in Python?
