Java 如何使用嵌套循环分别输出整数及其展开形式的幂

我想输出功率表，从n（0）到n（10），仅使用扫描仪输入底座

现在，我在设置它时遇到了困难

代码：

预期产出：

     5^0=
     5^1=
     5^2=
     5^3=
     - - - several lines are skipped here - - -
     5^10=

注意：这不是预期的输出，但我想自己尝试一下代码。这只是一个步骤，可以帮助我找到代码中的最终结果问题：

您在循环中使用了

result

，因此每次迭代都会重置它

您已将print语句放入循环中

您需要将

结果

与

base

相乘，每次迭代未完成

按如下方式操作：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);
        int option = keyboard.nextInt();
        int base = keyboard.nextInt();
        int exponent = keyboard.nextInt();
        int result = 1;
        if (option == 1) {
            for (int x = base; x <= base; x++) {
                if (exponent <= 1) {
                    System.out.print(base + "^" + exponent);
                } else {
                    System.out.print(base + "^" + exponent + "=");
                }
                for (int y = 1; y <= exponent; y++) {
                    System.out.print(exponent == 1 ? "" : (base + (y < exponent ? "*" : "")));
                    result *= base;
                }
                System.out.print("=" + result);
            }
        }
    }
}

根据你的评论，你还没有学会，但我强烈建议你学会。以下给出的解决方案不使用三元运算符：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);
        int option = keyboard.nextInt();
        int base = keyboard.nextInt();
        int exponent = keyboard.nextInt();
        int result = 1;
        if (option == 1) {
            for (int x = base; x <= base; x++) {
                if (exponent <= 1) {
                    System.out.print(base + "^" + exponent);
                } else {
                    System.out.print(base + "^" + exponent + "=");
                }
                for (int y = 1; y <= exponent; y++) {
                    if (y < exponent) {
                        System.out.print(base + "*");
                    } else if (exponent != 1) {
                        System.out.print(base);
                    }
                    result *= base;
                }
                System.out.print("=" + result);
            }
        }
    }
}
