file path Windows format to java format

Java 7 and up supports the Path class (in java.nio package). You can use this class to convert a string-path to one that works for your current OS.

Using:

Paths.get("\\folder\\subfolder").toString()

on a Unix machine, will give you /folder/subfolder. Also works the other way around.

Just check

in MacOS

File directory = new File("/Users/sivo03/eclipse-workspace/For4DC/AutomationReportBackup/"+dir);
File directoryApache = new File("/Users/sivo03/Automation/apache-tomcat-9.0.22/webapps/AutomationReport/"+dir); 

and same we use in windows

File directory = new File("C:\\Program Files (x86)\\Jenkins\\workspace\\BrokenLinkCheckerALL\\AutomationReportBackup\\"+dir);
File directoryApache = new File("C:\\Users\\Admin\\Downloads\\Automation\\apache-tomcat-9.0.26\\webapps\\AutomationReports\\"+dir);

use double backslash instead of single frontslash

so no need any converter tool just use find and replace

"C:\Documents and Settings\Manoj\Desktop" to "C:\\Documents and Settings\\Manoj\\Desktop"

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
path = path.replace("\\", "/");
// or
path = path.replaceAll("\\\\", "/");

Find more details in the Docs

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
String javaPath = path.replace("\\", "/"); // Create a new variable

or

path = path.replace("\\", "/"); // Just use the existing variable

Strings are immutable. Once they are created, you can't change them. This means replace returns a new String where the target("\\") is replaced by the replacement("/"). Simply calling replace will not change path.

The difference between replaceAll and replace is that replaceAll will search for a regex, replace doesn't.
