What java methods to use?

[blackcarlos Dibia]

pls what methods can be used to convert a number to binary then to an octet
and finnally to a Hexdecimal
I know of the toBinary()
for the rest help

[Luciano Mantuaneli]

If you don't bother in receive those convertions in a String format, you can use the Integer's methods:

toBinaryString(int)

toOctalString(int)

toHexalString(int)

However, if you declare an int variable and atribute a number prefixed with the zero digit, you assigning an actal value. The same happens for an hax value, if you prefix the number with "0x".

  
public class OctHexDecBin {
public static void main(String[] args) {
int value = 15;

System.out.println(Integer.toBinaryString(value));;
System.out.println(Integer.toOctalString(value));
System.out.println(Integer.toHexString(value));

value = 010;
System.out.println(value);
value = 0x10;
System.out.println(value);
}
}

thanks a lot
but I have already tried that may be I need to fully illustrate what
I want
I have a number say 236009 then convert to string then to octet and finally
to hexidecimal output
is this possible???

[Luciano Mantuaneli]

I guess there is no such thing in Java...

It really looks to me like this question has already been answered. For example:

        int value = 236009;
        System.out.println("Decimal: " + value);
        System.out.println("Binary: " + Integer.toBinaryString(value));
        System.out.println("Octal: " + Integer.toOctalString(value));
        System.out.println("Hex: " + Integer.toHexString(value));

Gives output:

Decimal: 236009
Binary: 111001100111101001
Octal: 714751
Hex: 399e9

Now if this isn't what you want...what sort of output are you expecting instead?

I think you require the following :

Decimal I/P : Binary O/P - using toBinaryString(int i). You can also use toString(int i,2)

Binary I/P : Octal O/P - as far a I know there's no method . So you can convert the binary input to Decimal value and then use toOctalString(int i) or toString(int i,8)

Octal I/P : Hex O/P - similar to above ..

Better suggestions are welcome !

hello black carlos.........
my suggestion to you is to write your own methods for conevrting to binary and to octal rather that using any java method.
This will help you to improve your programming skill.
