如何使用Stacks將Decimal轉換爲Binary to HexaDecimal轉換？

-1

這裏是我已經做代碼：如何使用Stacks將Decimal轉換爲Binary to HexaDecimal轉換？

import java.util.Stack; 

import java.util.Scanner; 

public class Conversion { 

public static void main(String[] args) { 

    Stack<Integer> s = new Stack<>(); 
    Scanner sc = new Scanner(System.in); 


    System.out.println("Enter a Number:"); 
    int numb =sc.nextInt(); 

    while(numb!=0){ 
     int bin = numb%2; 
     s.push(bin); 
     numb /=2; 
    } 
    System.out.println("Binary:"); 
    while(!(s.isEmpty())){ 
     System.out.print(s.pop()); 
    } 
    System.out.println(); 
    } 

}

我的問題已經是我的問題，正如你可以在這裏看到的是，我已經取得了二進制轉換，我不知道開始

'System.out.printf（「二進制：％S％N」，Integer.toBinaryString（麻木））;' –

那我怎麼還實現了其他2個是八和十六進制只使用棧 – blitzboy01

爲什麼？ ['Integer']（https://docs.oracle.com/javase/8/docs/api/java/lang/Integer.html）也有'toOctalString（int）'和'toHexString（int）'。 –

堆棧在被彈出之前需要被克隆，因爲堆棧一旦被彈出就變成空的。

import java.util.Stack; 
import java.util.Scanner; 

public class Conversion { 

    public static void main(String[] args) { 

     Stack<Integer> s = new Stack<Integer>(); 
     Scanner sc = new Scanner(System.in); 

     System.out.println("Enter a Number:"); 
     int numb = sc.nextInt(); 

     while (numb != 0) { 
      int bin = numb % 2; 
      s.push(bin); 
      numb /= 2; 
     } 

     Stack<Integer> st = (Stack<Integer>) s.clone(); // Added this line 

     System.out.println("Binary:"); 
     while (!(s.isEmpty())) { 
      System.out.print(s.pop()); 
     } 
     System.out.println(); 

     System.out.println("Octal: " 
       + changeBase((Stack<Integer>) st.clone(), 8)); // Added this line 
     System.out.println("Hexadecimal: " 
       + changeBase((Stack<Integer>) st.clone(), 16)); // Added this line 
    } 

    public static String changeBase(Stack<Integer> st, int base) { 
     StringBuilder result = new StringBuilder(); 
     int length = st.size(); 

     int bitsPerDecimal = 0, base_copy = base; 
     while (base_copy > 1) { 
      base_copy /= 2; 
      ++bitsPerDecimal; 
     } 

     int padding = bitsPerDecimal - (length % bitsPerDecimal); // make size of stack multiple of bitsPerDecimal 
     for (int i = 0; i < padding; ++i) { 
      st.push(0); 
     } 

     while (!st.empty()) { 
      int no = 0, pow = base; 
      for (int i = 0; i < bitsPerDecimal; ++i) { // Get the required bits to make a digit 
       pow /= 2; 
       no = no + pow * st.pop(); 
      } 
      if (no > 9) 
       result.append((char) ('A' + (no - 10))); 
      else 
       result.append(Integer.toString(no)); 
     } 
     return result.toString(); 
    } 
}
