encoding special characters in java

Question

I have a string message to display which contains special characters but it doesnt print all. For example if I give message like "The P & A company does the work". It prints only "The P".

public void setOutageMsg(String outageMsg) {
        //outage msg issue
        if(outageMsg==null){
            this.outageMsg = outageMsg;
        }
        else{
            outageMsg=outageMsg.replaceAll("&amp;","&").replaceAll("&","%26");  
            this.outageMsg = outageMsg;
        }
    }

Similarly, I need to have a single code for all the special characters.

When you say "it doesn't print all" how are you trying to print the message? Can you please provide the code you're using to print the message? — Samuel, Apr 25 '17 at 04:22
Are you supplying this through a web page? If so, you'd have to deal with the `&` character _before_ this method, not within it. — Dawood ibn Kareem, Apr 25 '17 at 04:24
public void setOutageMsg(String outageMsg) { //outage msg issue if(outageMsg==null){ this.outageMsg = outageMsg; } else{ outageMsg=outageMsg.replaceAll("&","&").replaceAll("&","%26"); this.outageMsg = outageMsg; } } — Sakshi Jauhari, Apr 25 '17 at 15:06
the above code worked correctly for '&' encoding but i need to have a code which works for all special characters " !@#$%*()............" any suggestions? — Sakshi Jauhari, Apr 25 '17 at 15:07

Try this, It may help you

outageMsg=outageMsg.replaceAll("&amp;","&").replaceAll("&","\u0026");

or

outageMsg=outageMsg.replaceAll("&(?!amp;)","&").replaceAll("&","\u0026");

thanks for the suggestion. The code for '&' works. Now I need to encode for all the special characters which includes " % *#@()!" and do not want to seperately encode each and every character.Any suggestions? – Sakshi Jauhari Apr 25 '17 at 13:16
Answer is right so why i was down voted ? any ways your string can have all special characters or you need replace for looking for "% *#@()!" only ? – Vinit Solanki Apr 25 '17 at 14:40
string can have all special characters. – Sakshi Jauhari Apr 25 '17 at 15:01
"&(?!amp;)" is regex, you can for other special characters as well – Vinit Solanki Apr 25 '17 at 15:05
I dont want to add seperate line of code encoding for all characters instead 1 code which will encode all special chars when i pass a String – Sakshi Jauhari Apr 25 '17 at 15:09
suppose you are replacing "&(?!amp;)" with "&", and then what other special character will replace with ? Actually you need use replaceAll method for each and every special character. – Vinit Solanki Apr 25 '17 at 15:12

You can write something along these lines

    public void setOutageMsg(String outageMsg) {
            //outage msg issue
            if(outageMsg==null){
                this.outageMsg = outageMsg;
            }
            else{
                this.outageMsg = getFormattedString(outageMsg);
            }
        }

    private String getFormattedString(String outageMsg){
           outageMsg.replaceAll("&amp;","&");
           outageMsg.replaceAll("a","b");
           //...
           return outageMsg;
       }
