以下是Java实现十进制到各种进制的转换的代码示例：

import java.util.Scanner;

public class DecimalToOtherBases {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter a decimal number: ");
        int decimalNumber = scanner.nextInt();
      
        System.out.println("Binary: " + convertToBase(decimalNumber, 2));
        System.out.println("Octal: " + convertToBase(decimalNumber, 8));
        System.out.println("Hexadecimal: " + convertToBase(decimalNumber, 16));
      
        scanner.close();
    }
  
    public static String convertToBase(int decimalNumber, int base) {
        if (decimalNumber == 0) {
            return "0";
        }
      
        StringBuilder result = new StringBuilder();
        while (decimalNumber > 0) {
            int remainder = decimalNumber % base;
            if (remainder < 10) {
                result.insert(0, remainder);
            } else {
                result.insert(0, (char) ('A' + remainder - 10));
            }
            decimalNumber /= base;
        }
      
        return result.toString();
    }
}

这段代码可以让用户输入一个十进制数，然后将其转换为二进制、八进制和十六进制表示。实现了基本的转换功能，满足你的要求。
