binary conversion?

hi people,

how we can convert alphabets like a,b,c,d into binary form?can any one reply to this urgently needed please

Hello vinay,

I suppose this question should be asked in Java Beginner forum, this is certification related.
Please use meaningful subject line as well.

Best Regards,

What exactly do you mean? do you want to come up with your own conversion? then you can do it however you want.

If you want to know how the character 'a' would be stored natively by java, i'd start by looking at a ASCII table.

start with "a"

ascii decimal for "a" ?

97

how to convert decimal into binary?

0 = 00000000
1 = 00000001
2 = 00000010
.
.
.
7 = 00000111
8 = 00001000

keep finding closest power of 2
2 to the 6th is 64
+
2 to the 5 is 32

makes 96

plus 1 is
97

so in decimal that should be
01000000 = 64
+
00100000 = 32
+
00000001 = 1
_____
01100001 = 97 = a

This doesn't make sense. In java, and in fact all computing languages and computers in general, everything is stored in binary. that's all they understand are 1's and 0's. so, what you see as an 'a' is really stored as a number, and that is stored as a binary number. It all happens automatically.

So tell us what you really want to do. do you want to save the number? do you want to print the number value? do you want to use the pre-defined ASCII values, or come up with your own?

The single most important part of writing code is understanding what you want to do, and spec it out.
