Errors in Regular Expression example on Eclipse

[Rajiv Rai]

Hi
I am currently reading the regular expression tutorial provided by Oracle.

Following is a test program for understanding regex

import java.io.Console;
import java.util.regex.Pattern;
import java.util.regex.Matcher;

public class RegexTestHarness {

    public static void main(String[] args){
        Console console = System.console();
        if (console == null) {
            System.err.println("No console.");
            System.exit(1);
        }
        while (true) {

            Pattern pattern = 
            Pattern.compile(console.readLine("%nEnter your regex: "));

            Matcher matcher = 
            pattern.matcher(console.readLine("Enter input string to search: "));

            boolean found = false;
            while (matcher.find()) {
                console.format("I found the text" +
                    " \"%s\" starting at " +
                    "index %d and ending at index %d.%n",
                    matcher.group(),
                    matcher.start(),
                    matcher.end());
                found = true;
            }
            if(!found){
                console.format("No match found.%n");
            }
        }
    }
}

When i try to run the above code example in eclipse it returns the Console object as null..
Hence the example cant run further.
What modifications do i have to do so that it runs in eclipse as well

Thanks

Hi Rajiv,

The Eclipse team are looking at fixing this - https://bugs.eclipse.org/bugs/show_bug.cgi?id=122429

As a workaround to get your example going, you can use System.in - so something like:

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
String line = bufferedReader.readLine();
