Ejemplo 3: programa Java para convertir números decimales a binarios y contar el número de 1s

// decimal to binary conversion in java
import java.util.Scanner;
public class DecimalBinaryDemo
{
   public static void main(String[] args)
   {
      int number, count = 0, temp;
      String strConvert = "";
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter a decimal number : ");
      number = sc.nextInt();
      // decimal to binary java
      while(number > 0)
      {
         temp = number % 2;
         if(temp == 1)
         {
            count++;
         }
         strConvert = strConvert + " " + temp;
         number = number / 2;
      }
      System.out.println("Decimal to binary in java : " + strConvert);
      System.out.println("Number of 1s : " + count);
      sc.close();
   }
}

Ejemplo 4: binario a entero en java

System.out.println(Integer.parseInt("1010",2));

Ejemplo 5: Java convierte binario a decimal

import java.util.Scanner;
public class BinaryToDecimalDemo 
{
   public static void main(String[] args) 
   {
      int number, decimal = 0, a = 0;
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter binary number: ");
      String strBinary = sc.nextLine();
      number = Integer.parseInt(strBinary);
      while(number != 0){
         decimal += (number % 10) * Math.pow(2, a);
         number = number / 10;
         a++;
      }
      System.out.println("Decimal number: " + decimal);
      sc.close();
   }
}

Ejemplo 6: programa Java para convertir decimal a binario usando toBinaryString y stack

Convert decimal to binary using toBinaryString() method
public class DecimalToBinary
{
   public static void main(String[] args)
   {
      System.out.println("decimal to binary using toBinaryString() 104: ");
      // to binary string java
      System.out.println(Integer.toBinaryString(104));
      System.out.println("ndecimal to binary using toBinaryString() 554: ");
      // tobinarystring
      System.out.println(Integer.toBinaryString(554));
      System.out.println("ndecimal to binary using toBinaryString() 644: ");
      System.out.println(Integer.toBinaryString(644));
   }
}
