How to determine whether a file exists in java

java determines whether a file exists:

public static String fileExists(String plainFilePath){
File file=new File(plainFilePath);
if(!file.exists()) {
return "false";
} else{

return "true";
}
}

file_exists is a function whose Chinese name is to check whether a file or directory exists. (If under Linux. The permission of the parent folder that needs to be detected is not 777, false will be returned)

bool file_exists ( string filename )

If the file or directory specified by filename exists, it will return TRUE, otherwise it will return FALSE.

In Windows, use //computername/share/filename or \\computername\share\filename to check shared files on the network.
