第五章第三十八题（十进制转换八进制）(Decimal to octal)

• **5.38（十进制转换为八进制）编写程序，提示用户输入一个十进制整数，然后显示对应的八进制值。在这个程序中不要使用Java的Integer.toOctalString(int)方法。
  **5.38(Decimal to octal) Write a program that prompts the user to enter a decimal integer and displays its corresponding octal value. Don’t use Java’s Integer.toOctalString(int) in this program.
• 参考代码：

package chapter05;import java.util.Scanner;public class Code_38 {
    public static void main(String[] args) {
    String octalString = "";int decimalNumber;System.out.print("Enter a decimal integer: ");Scanner inputScanner = new Scanner(System.in);decimalNumber = inputScanner.nextInt();do {
    octalString = decimalNumber % 8 + octalString;decimalNumber /= 8;}while(decimalNumber > 0);System.out.printf("Its corresponding octal value is %s", octalString);}
}

• 结果显示：

Enter a decimal integer: 45
Its corresponding octal value is 55
Process finished with exit code 0
