I want to convert a string into a binary string.

I have tried

String str = "123";
int foo1 = Integer.valueOf(str);
String strbinary = Integer.toBinaryString(foo1);

It is giving the correct result but it is not useful because the output I am getting is 1111011, but the desired output is 01111011.

Is there some other better way to convert string into binary? I want it 0-padding, in my case for 0-padding I want it just an even binary string, doesn't want everytime 16 digit binary as in this case

 String.format("%16s", Integer.toBinaryString(1)).replace(' ', '0')

What's wrong with the given output? That it's not padded? Just pad it yourself. – Sotirios Delimanolis May 24 '15 at 04:15

Also the code gives an error. I guess the first line should be `String str = "123";` – Chintan May 24 '15 at 04:21
@SotiriosDelimanolis....I do not want it to be of 16digits everytime... is there some other way? – Gungun May 24 '15 at 05:12
