Answer 1

public class IntegerToStringBinary {

public static void main(String argv[]){
int num = 105; //enter your integer number here
System.out.println(convertToBinary(num));
}

public static String convertToBinary(int number)
{
if(number > 0)
{
String str1 = new String(convertToBinary(number / 2));
String str2 = new String(str1+Integer.toString(number % 2));
return str2;
}

return "0";
}
}
