🔴 AI 代码审查发现问题

📋 问题概述

数组越界访问风险
line 5-7 仅校验了 pos < 0 的下限，但未校验 pos >= store.length 的上限。当调用者传入 pos >= 4 时（如 line 12 的 putData(5, 100)），line 8 会触发 ArrayIndexOutOfBoundsException。

📍 问题详情

🔴 问题 1 | 严重程度: HIGH | 行号: 8

💬 详细说明：

  • 任何调用 putData 且传入非法索引的代码都会导致运行时异常崩溃。虽然 Java 有边界检查不会造成内存破坏，但会导致服务不可用或数据丢失。

📝 问题代码：

        store[pos] = num;

💡 修复建议：

在 line 5 的条件中增加上限检查，确保 pos 在 [0, store.length) 范围内。

✅ 修复示例：

    public static void putData(int pos, int num) {
        if (pos < 0 || pos >= store.length) {
            return;
        }
        store[pos] = num;
    }
