Absolute and relative paths to "Java"

Here is the directory path to differentiate
Such as:

/opt/deve/tomcat/bin
C:\deve\tomcat\bin
are absolute directory paths

Bin
Bin/data
Bin\data
are relative directory paths

by observing, discovering the law

Either start or include \ or//are absolute paths or
To/start or include: absolute path
The opposite is the relative path.

Introduce several methods:

1. StartsWith
   

2. public class Stringutil {
   

3. public static void Main (string[] args) {
   

4. String Path = "/opt/bin";
   

5. System.out.println (Path.startswith ("/"));
   

6. }
   

7. }
   

8. 
   

9. Result: True
   

10. 
    

11. IndexOf

Copy Code

Final Result:

1. 
   

2. public boolean Isabsolutepath (String path) {
   

3. if (Path.startswith ("/") | | path.indexof (":") > 0) {
   

4. return true;
   

5. }
   

6. return false;
   

7. }
