The reason why the specified path cannot be found when creating a file in java

When creating a file, it prompts that the specified path cannot be found. This is because the directory has not been created. (Recommended: java video tutorial)

For example, create a file:

File file = new File(“C:/test.txt”); 
file.createNewFile();

This is correct, no If any errors occur, throw an exception.

But this resulted in the exception "The system cannot find the specified path":

File file = new File(“C:/test/test.txt”); 
file.createNewFile();

I found the answer later. The problem lies in: when you create a file, you should first Create the file's parent directory (unless you created the parent directory manually).
This is how to write a file that creates a multi-level directory:

File fileDir = new File(“C:/test/”); 
fileDir.mkdirs(); 
File file = new File(“test.txt”); 
file.createNewFile();
