String to Binary?

I am trying to take a sting ie. "hello" and convert it to binary. I think if I broke it down into char and used digit() it may work? But I don't understand the syntax to use digit() or maybe it's forDigit()? Any other pointers please include. Any help greatly appriciated.

I need more help!

Are you sure this kind of conversion a meaningful task ?

You break the String down into an array of char by calling getChar() on it. You can then get the int value of each char using the Integer.toBinaryString() method to convert each char to a binary String representation as in the following code fragment:

Is this what you are trying to do ?
It's unclear from your post exactly what you mean by "convert it to binary".
Character.digit() converts a char that represents a digit in some radix to the equivalent int.
