选择性目录的 Java 编译错误

Question

javac 文件名.java 不工作于 “C:\Users\Idiot\OneDrive\Documents\NiT\第 5 学期\OOP with Java\LAB\DAY_1” 但工作得很好 “D:”

我已经尝试将路径设置为 “C:\Program Files\Java\jdk-12.0.2\bin”

您的用户是否可能无权使用 Java\LAB\DAY_1\写入 C:\Users\Idiot\OneDrive\Documents\NiT\5th Semester\OOP ？ 您可以在该目录中手动创建文件吗？ 路径中的空格也可能会导致问题。通常应该避免这些。
