Convert IP address to array of bytes

[Gunner 1]

Hello,
My problem: I have a String that contains an IP address and I would convert every byte in an array of byte []. This is what I try to do for achieving this, but unfortunately this is not working
Here is my code

StringTokenizer stok = new StringTokenizer(sourceIPAddress, ".");
String oc4 =  "0x" + Integer.toHexString(Integer.parseInt(stok.nextToken()));
String oc3 =  "0x" + Integer.toHexString(Integer.parseInt(stok.nextToken()));
String by2 =  "0x" + Integer.toHexString(Integer.parseInt(stok.nextToken()));
String by1 =  "0x" + Integer.toHexString(Integer.parseInt(stok.nextToken()));

Any help on this is highly appreciated. Thanks in advance.

Hello,
You can pass instead of the integer to a Byte.
Here is the method, how you can do this

Byte mnby = (byte) Integer.parseInt(token)

where token is a part of your address. And attention to the limits, because it may give any exception for the code if not used properly. If you have any more queries regarding this topic then you can post and we will try to solve your query.

Hello,
Here is an sample example for the same, see, if this helps you.

String st = "IP address";
String[] strar = st.split("\\.");
Short[] sh = new Short[Aft.length];
for(int i =0; i <strar.length; i + +){
  sh[i]=Short.function valueOf() {
    [native code]
}(strar[i]);
}

Hello,
The Class InetAddress offers everything you need:
Here is an example of what it is capable of.

	InetAddress ad = InetAddress.getByName("IP address ");
	byte[] ip = ad.getAddress();

The java.io and java.net packages are important in your case. I recommend you to study the java.io and the java.net packages and then code for your program what you are trying to develop.

Hello,
I have tried this code, the InetAddress class does not do what I want.
Here is the code which I have tried

InetAddress ad = InetAddress.getByName("IP address");
byte[] by = ad.getAddress();
System.out.System.out.println(by[0]);
System.out.System.out.println(by[1]);
System.out.System.out.println(by[2]);
System.out.System.out.println(by[3]);

If you have any other alternative method which can do the same or give the same result then please do post back.

Hello,
Just have a look at the following part of code

int oc = Integer.parseInt(st.nextToken());

Indeed it is no use to format a number to string for call in number. In short your problem is a display problem.

	InetAddress ad = InetAddress.getByName("IP address");
	byte[] by = ad.getAddress();

And this

System.out.printf("% # x% # x% # x% # x% n", i[0], i[1], i[2], i[3] );
