Java 程序将十进制转换为八进制

在本文中，我们将了解如何将十进制转换为八进制。十进制数是由小数点分隔整数和小数部分的数。八进制数的基数为八，使用 0 到 7 之间的数字。

下面是对同一内容的演示 −

输入

假设我们的输入为 −

Enter the decimal number : 8

输出

所需的输出为 −

The octal value is
10

算法

Step 1 - START
Step 2 - Declare three integer value namely my_input, I and j and an integer array my_octal
Step 3 - Read the required values from the user/ define the values
Step 4 – Using a while condition of input not equal to 0, compute my_input % 8 and store it
to my_octal[i]
Step 5 - Compute my_input / 8 and assign it to ‘my_input’, increment ‘i’ value.
Step 6 – Iterating using a for loop, print the ‘my_octal’ array
Step 7- Stop

示例 1

此处，用户根据提示输入。你可以在我们的编码工具 运行按钮中实时试用此示例。

import java.util.Scanner;
public class DecimalToOctal {
   public static void main(String[] args){
      int my_input, i, j;
      System.out.println("Required packages have been imported");
      Scanner my_scanner = new Scanner(System.in);
      System.out.println("A reader object has been defined ");
      System.out.print("Enter the decimal number : ");
      my_input = my_scanner.nextInt();
      int[] my_octal = new int[100];
      System.out.println("The octal value is ");
      i = 0;
      while (my_input != 0) {
         my_octal[i] = my_input % 8;
         my_input = my_input / 8;
         i++;
      }
      for ( j = i - 1; j >= 0; j--)
         System.out.print(my_octal[j]);
   }
}

示例 2

此处，该整数已经事先定义，并且获取其值并显示在控制台中。

public class DecimalToOctal {
   public static void main(String[] args){
      int my_input, i, j;
      my_input = 8;
      System.out.println("The decimal number is defined as " +my_input);
      int[] my_octal = new int[100];
      System.out.println("The octal value is ");
      i = 0;
      while (my_input != 0) {
         my_octal[i] = my_input % 8;
         my_input = my_input / 8;
         i++;
      }
      for ( j = i - 1; j >= 0; j--)
         System.out.print(my_octal[j]);
   }
}

输出

The decimal number is defined as 8
The octal value is
10
