Pseudocode in java? [closed]

问题

 String s = ""; 

    myf = new Finch();
    do
    {
        //Run the menu until quit or cancel is selected
        s = FinchMenu();
        //menu 1
        if (s.equals("Back and forward")) RunAccelerationTest(s);
    }

How would you convert something like this to pseudocode? For instance

String s = "";

Would the pseudocode for it be something like this?

Set s to ""

That just seems wrong to me.

Any help please? Thanks

Pseudocode, i think, doesn't have a predefined syntax. just follow two rules:

It should be plain english with common programming constructs.
It should be generic, not specific to any language.

Following should fit:

Step 1: Initialize an empty string. (say str)

Step 2: Construct a new 'Finch' object.

Step 3: BEGIN LOOP

            Fetch 'FinchMenu' from 'Finch' object.

            assign 'FinchMenu' to 'str'

            IF 'FinchMenu' is "Back and forward"

                Call 'RunAccelerationTest' method with 'str' as argument.

            END IF

        END LOOP

Pseudo code is just a non language specific human readable walkthrough of whatever it is you are trying to do.

You could write set s to "" or even make s an empty string or anythign else that describes what it is this step is doing.

Generally speaking (this is totally how I use pseudo-code, rather than being anything set by a rule) I use pseudo-code to get rid of anything boilerplate or being syntactically correct.

For instance, say I have the following Java code...

import java.io.*;
class FileRead 
{
 public static void main(String args[])
  {
  try{
  // Open the file that is the first 
  // command line parameter
  FileInputStream fstream = new FileInputStream("textfile.txt");
  // Get the object of DataInputStream
  DataInputStream in = new DataInputStream(fstream);
  BufferedReader br = new BufferedReader(new InputStreamReader(in));
  String strLine;
  //Read File Line By Line
  while ((strLine = br.readLine()) != null)   {
  // Print the content on the console
  System.out.println (strLine);
  }
  //Close the input stream
  in.close();
    }catch (Exception e){//Catch exception if any
  System.err.println("Error: " + e.getMessage());
  }
  }
}

My interpretation as pseudo-code would be something like...

main() {
FileInputStream fstream = new FileInputStream(fileLocation);
BufferedReader br = BufferedReader(.....fstream);
String str;
while(br.readline!=empty, str=br.readline) {
  System.out(str);
}
}

Now this code is probably no use to anyone but me - but I know I can quickly look at it, see what it is and write it if necessary. It's good for making quick notes in meetings etc, if I'm trying to write fast pseudo-code, things like exception handling aren't something I consider.
