Instructions

In groups of 2-3, using either pseudocode, Java code, or written instructions, describe how you would implement the method:

public String decimalToBinary(int address)

Precondition: address is a non-negative integer < 32768

Postcondition: return value must be a String of length 16
Please post your ideas (or solution) to this Padlet.
Optionally, attach an image or diagram if it helps illustrate your work

int result = address;

int remainder;

String binary = "";

while(result!=0) {

remainder = result % 2;

result = result / 2;

binary = remainder + binary;

}

while(binary.length < 16) binary = '0' + binary;

return binary;

StringBuilder res = new StringBuilder();

int div = address;
int rem;

while (div != 0) {
    rem = div % 2;
    div /= 2;

    res.append(rem);
}

while(res.length() != 16) {
    res.append('0');
}

return "0b"+ res.reverse();

int dividend = 20;

int bit = 0;

int bitmask = 1;

int i = 0;

bits = "";

while (bitmask < 65536)

{

bit = (dividend & bitmask) >> i;

bitmask = bitmask << 1;

i++;

bits = Integer.toString(bit) + bits;

}

System.out.println(bits);

final int MAX = 32768;
int remainder [] = new int [16] ;
String result = "";
int count = 0;
if(address < 32768 && address >= 0){
    while(address > 0){
        remainder[count++] = address % 2;
        address = address / 2 ;
    }
    for (int i = 15; i>=0; i--){
        result = result +  remainder[i];
    }
