java编程怎么编？

Question

利用Random类来产生5个50~100之间的随机整数。输出它的二进制、八进制和十六进制表示形式。怎么编？

Answer 1

package Test07;

import java.util.Random;

public class Test01 {
    public static void main(String[] args) {
        Random rand = new Random();
        int[] num = new int[5];
        for (int i = 0; i < num.length; i++) {
            // 随机产生50~100的随机数
            num[i] = 50 + rand.nextInt(111);
            // 输出进制
            System.out.println(num[i]);
            System.out.println(num[i] + "二进制为：" + Integer.toBinaryString(num[i]));
            System.out.println(num[i] + "八进制为：" + Integer.toOctalString(num[i]));
            System.out.println(num[i] + "十六进制为：" + Integer.toHexString(num[i]));
        }

    }
}

结果

望采纳，谢谢！
