Relative path and absolute path in Java

Paths in JavaSE are divided into absolute paths and relative paths:

1. Relative path: project name/ (up to resource name)
2. Absolute path: drive letter:/directory/file name

Paths in JavaEE are also divided into absolute paths and relative paths:

1. Relative path:
   . Indicates the current file directory
   .. Indicate the parent directory of the current file
   name indicates the files in the current directory, which is equivalent / filename
   / can be ignored

2. Absolute path:
   http://ip address/project name/resource path
