Do you mean with two's complement representation of -ves? You'll have to decide that before you work on the conversion. If you do, you could cheat and look at the source of Integer.toBinaryString: public static String toBinaryString(int i) { return toUnsignedString(i, 1); } /** * Convert the integer to an unsigned number. */ private static String toUnsignedString(int i, int shift) { ... |

It's best if you start with an example you can work out by hand. You can examine what happens and write code to accomplish it.

The problem sounds poorly phrased. Apparently, what you're doing is getting a string of user input, which represents a binary number, but reading it as an int. Then you're converting that int into another int. But the int you've read in isn't really binary, any more than the number you produce is binary. (They're both binary in that they're stored in ... |

I think you can do this by using the java.lang package since it provides the facility to convert the integer data into the binary to decimal. Also, you may use the parseLong() method to parse the string argument as a signed decimal long. By the way, the type of loop you need is a while loop. If anything, ask more questions. ... |

As others have said, I'd have to agree you need to figure out how to use a loop. I haven't looked at any of your previous posts, but, trust they have.

You convert those steps procedurally - so for the decimal to binary one you could maybe have some sort of a loop that runs until the division is complete - each time printing the result to an array? Then you could have some method that reverses the Array to give you your binary. You have to think outside the box a ... |
