how to print 4 binary value in python code example

Example 1: addition of array in python with input

#Python program to add all the array elements using the built-in function
lst = []
num = int(input("Enter the size of the array: "))
print("Enter array elements: ")
for n in range(num):
  numbers = int(input())
  lst.append(numbers)
print("Sum:", sum(lst))

Example 2: how to get the binary value in python

bin(19) # will return '0b10011'

#or you can do

def binary(num):
    array = []

    #makes the binary value
    while(num > 0):
        sol1 = num / 2

        check = sol1 - int(sol1)

        if(check > 0):
            array.append("1")
            num = sol1 - 0.5
        else:
            array.append("0")
            num = sol1
            
    #makes sure the binary value is a minimum of 4 bits long
    while(len(array) < 4):
        array.append("0")

    #reverses the array
    array = array[::-1]

    #joins the array into a string, return the string
    string = ''.join(array)

    return string
  
#binary(19) will return 10011

Example 3: how to get binary value in java

import java.util.*;

class Bin {

    //fields
    private Double number;

    //constructors
    public Bin(){
        number = 0.0;
    }

    public Bin(Double num){
        number = num;
    }

    //methods
    public ArrayList<String> reverseArrayList(ArrayList<String> alist) {
        
        ArrayList<String> array = new ArrayList<String>();

        int x = 0;
        int i = alist.size() - 1;

        while(x < alist.size()){
            array.add(alist.get(i));
            i -= 1;
            x += 1;
        }

        return array;
    }

	//getter methods
    public ArrayList<String> getBinVal(){
        ArrayList<String> binaryVal = new ArrayList<String>();
        ArrayList<String> array = new ArrayList<String>();
        Double num = number;
        Double sol1, check; 

        while( num > 0 ) {

            sol1 = num/2;
            check = sol1 - Math.floor(sol1);

            if(check > 0) {
                binaryVal.add("1");
                num = sol1 - 0.5;
            }

            else {
                binaryVal.add("0");
                num = sol1;
            }
        }

        while(binaryVal.size() < 4) {
            binaryVal.add("0");
        }

        array = reverseArrayList(binaryVal);
        return array;
    }

}

class MainClass {
    
    public static void main(String[] args) {
		
      	//add the number in as a command line argument
        Double num = Double.valueOf(args[0]);
		
      	//create an instance of Bin
        Bin value = new Bin(num);
		
      	//print the binary value
        System.out.println(value.getBinVal());
    }
}
