• editing a string using BufferedReader in Java

  - by pbs

  Exception handling aside, I'm using the following to input a line of text in Java: BufferedReader strin = new BufferedReader(new InputStreamReader(System.in)); String txt = null; txt = strin.readLine(); However, I want to be able to edit an existing string, so that if txt were initialized to "hello" instead of null, then the readLine() would have the "hello" text in the buffer for me to edit. I can't see how to do this. Any help would be appreciated.

• Multiple Regex on String

  - by George

  How can I apply multiple regexs to a single string? For instance, a user inputs the following into a text area: red bird blue cat black dog and I want to replace each carriage return with a comma and each space with an underscore so the final string reads as red_bird,blue_cat,black_dog. I've tried variations in syntax along the lines of the following so far: function formatTextArea() { var textString = document.getElementById('userinput').value; var formatText = textString.replace( new RegExp( "\\n", "g" ),",", new RegExp( "\\s", "g"),"_"); alert(formatText); }
