How to given a fixed path to eclipse

Question

Code:

InputStream inputStream = System.in;
InputReader in = new InputReader(inputStream);

How could I modify this code to take a file from a fixed location?

Equivalent scanner example:

Scanner in = new Scanner(new InputStreamReader(System.in));
Scanner in = new Scanner(new FileReader("C:\\Users\\Max\\Desktop\\yes.txt"));

I'm not sure what you're actually asking for but if you don't want to hard code the path (which is generally not advisable) you could use a property or argument to `main(...)` which can be set in your run configuration in Eclipse. — Thomas, Jul 22 '16 at 08:50
In Eclipse use `Run > Run Configurations...` and create a configuration for the type of application you want to run (most likely a "Java Application"). Then enter the path in the "Arguments" tab and finally run the configuration you just created (either via the "Run" button in the dialog or the run button in the menu bar which looks like a green "play" button). — Thomas, Jul 22 '16 at 08:55
You might want to read the documentation on that. Basically it depends on how you want to get the value. VM arguments would be properties (i.e. what you'd pass with `-Dxxx`) while program arguments would be what you pass to `main()`. — Thomas, Jul 22 '16 at 09:06

if you only want the whole text in one string than you can use the FileInputStream

FileInputStream inputStream = new FileInputStream("foo.txt");
try {
    String everything = IOUtils.toString(inputStream);
} finally {
    inputStream.close();
}

if you want to read the file line bye line use the BufferdReader in Connection with StringBuilder

BufferedReader br = new BufferedReader(new FileReader("file.txt"));
try {
    StringBuilder sb = new StringBuilder();
    String line = br.readLine();

while (line != null) {
    sb.append(line);
    sb.append(System.lineSeparator());
    line = br.readLine();
}
String everything = sb.toString();

}finally {
    br.close();
}

To read file using Scanner class.

Try this.

Scanner input=null;
try{
    input=new Scanner(new File("your_file_path\yes.txt"));
} catch(Exception ex){
    System.out.println(ex.getMessage());
}

while(input.hasNext()){
    System.out.println(input.next());
}

input.close();
