Java Web Development Techdegree Graduate 22,175 PointsIn Eclipse or other IDE you cannot use Console.readLine
, for detailed explanation why, see here:
http://stackoverflow.com/questions/26470972/trying-to-read-from-console-java
In order to prompt user for input in IDE commonly BufferedReader
or Scanner
are used. For what is better see here:
http://stackoverflow.com/questions/2231369/scanner-vs-bufferedreader
I prefer BufferedReader
, well I didn't dig up well Scanner
and I know how to mock BufferedReader
to test user input in Unit Testing. Here is code example how BufferedReader
can be used:
public static void main(String[] args) throws IOException {
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
String userInputString = "";
try {
userInputString = mBufferedReader.readLine();
} catch (IOException ioe) {
throw new IOException("Problems with reading user input");
}
// here you can use "userInputString"
}
