JAVA实现蓝桥杯基础练习十六进制转换八进制-----------拓展进制转换计算器
这个题目我浏览了大量的道友的文章发现十分麻烦，但仍然从其中收益菲薄，所以在这里分享一下我认为最好的代码

import java.math.BigInteger;
import java.util.Scanner;public class L2021java_prictise {
public static void main(String[] args) {Scanner scanner = new Scanner(System.in);int n = scanner.nextInt();BigInteger []a = new BigInteger[n];for (int i = 0;i < n;i++){a[i] = new BigInteger(scanner.next(),16);}
for(int j = 0;j < n;j++){System.out.print(a[j].toString(8)+"\n");
}
}
}

进阶版本的任意进制转换计算器：

import java.math.BigInteger;
import java.util.Scanner;public class L2021java_prictise {
public static void main(String[] args) {Scanner scanner = new Scanner(System.in);System.out.print("请输入被转换数个数："+"\n");int n = scanner.nextInt();System.out.print("请输入被转换数进制数："+"\n");int m = scanner.nextInt();System.out.print("请输入将要转为____进制？："+"\n");int t = scanner.nextInt();System.out.print("请输入你要转换的数字以回车分隔："+"\n");BigInteger []a = new BigInteger[n];for (int i = 0;i < n;i++){a[i] = new BigInteger(scanner.next(),m);}
for(int j = 0;j < n;j++){System.out.print(a[j].toString(t)+"\n");
}
}
}

希望对大家有所帮助，求赞！！！！
