Question

I have a number 83 I want to split this number like 8 and 3 then want to change the number into binary form in android and want the result.how can I do this.Please help me

Thanks

Answer 1

You can convert an integer value to binaryString using Integer.toBinaryString(int) .

Now, to split your integer into individual digits, you can use simple mathematics using modulus (%) and division (/) operators.

Here's the recursive function that you can use: -

public static void convert(int num) {

    if (num > 0) {
        int lastDigit = num % 10;
        convert(num / 10);
        System.out.print(Integer.toBinaryString(lastDigit) + " ");
    }
}

// From your main method
convert(83);

OUTPUT: -

1000 11

Answer 2

To Get Digits from a number use following method:

String str = String.valueOf(someInt);

char[] digits = str.toCharArray();

now itereate through digits array. and convert each digit to binary, by

Integer.toBinaryString(Character.digit(digits[i], 10));

Answer 3

 public String conIntTOBin(String num) {
        String temp = "";

        for(int i=0; i < num.length(); i++) {                               
              temp += Integer.toBinaryString(Integer.parseInt(""+num.charAt(i)));
        }
        return temp;

 }

pass your integer number as a string perametre.
