Your binaryForm method is getting caught in an infinite recursion, you need to return if number <= 1:

Integer.toBinaryString() is an in-built method and will do quite well.

you will get a NumberFormatException error.

What I did to convert String x to Integers, was first converted each individual Char in the String x to a single Char in a for loop.

I then converted each Char back into an individual String,

then Parsed each String into an Integer.

Id figure Id post this, because I took me a while to figure out how to get a binary such as 01010101 into Integer form.

The following converts decimal to Binary with Time Complexity : O(n) Linear Time and with out any java inbuilt function

If you want to reverse the calculated binary form , you can use the StringBuffer class and simply use the reverse() method . Here is a sample program that will explain its use and calculate the binary

public class Binary {

}

public class Main {

}

It might seem silly , but if u wanna try utility function

there must be some utility method to do it directly, I cant remember.

Dec 07, 2016  People probably don't realize that there's quite a lot of Dead Rising games. Now that you do know, however, you're likely wondering which one is the best. Best dead rising games. Dead Rising 3 I still love too and while it went back to being more serious and felt more like a zombie survival, alot of the charm in the past two games were gone and the music, which the past ones had great soundtracks espcially with psychos, was barely around.

A rather simple than efficient program, yet it does the job.

All your problems can be solved with a one-liner! To incorporate my solution into your project, simply remove your binaryform(int number) method, and replace System.out.print(binaryform(number)); with System.out.println(Integer.toBinaryString(number));.

Or you can use Integer.toString(int i, int radix)

e.g:(Convert 12 to binary)

I just solved this myself, and I wanted to share my answer because it includes the binary reversal and then conversion to decimal. I'm not a very experienced coder but hopefully this will be helpful to someone else.

What I did was push the binary data onto a stack as I was converting it, and then popped it off to reverse it and convert it back to decimal.

You can use the concept of Wrapper Classes to directly convert a decimal to binary,hexadecimal and octal.Below is a very simple program to convert decimal to reverse binary .Hope it contributes to your java knowledge

Even better with StringBuilder using insert() in front of the decimal string under construction, without calling reverse(),

Well, you can use while loop, like this,

No need of any java in-built functions. Simple recursion will do.
