You should have only one bin directory for the JDK in the path at a time (those following the first are ignored), so if one is already present, you can update that particular entry. The following is an example of a PATH environment variable: C:\Java\jdk1.7.0\bin;C:\Windows\System32\;C:\Win...

java adding to path
Adding something to the path just makes the commands in the folder available everywhere system wide. The way an OS (not limited to Windows) works is that it searches certain folders for the commands you enter in the terminal (console). If it doesn't find the command, it tells you that the command you entered is not recognized. By adding a folder to the path you tell the OS to also search that particular folder when you enter a command. For Java, you need javac and java from the console. The former compiles your source code, the latter executes it. Had you not added the folder to the path, you would always need to type C:\Program Files\Java\jdk-17\bin\javac when you want to compile a program. By adding the folder to the path javac becomes sufficient. More on reddit.com

April 3, 2019Need help opening .JAR files
My file association is: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\.jar] @="jarfile" [HKEY_CLASSES_ROOT\jarfile\shell\open\command] @="\"C:\\Program Files\\Java\\jre1.8.0_144\\bin\\javaw.exe\" -jar \"%1\" %*" Try specifying javaw.exe (the hidden console version of 'java.exe') as the 'open with', then you may have to edit it to add the "-jar".

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.

Just set the path variable to JDK bin in environment variables.
Variable Name : PATH
Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin
But the best practice is to set JAVA_HOME and PATH as follow.
Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.8.0_31
Variable Name : PATH
Variable Value : %JAVA_HOME%\bin
