Question

When I grab the IP Address from my open socket, as someone has sent me a stream, I noticed that the IP has a forward-slash.

I just plan to simply omit it. But first I want to validate the first character in the string is the forward-slash:

String dataSource = data.getAddress().toString();

if(dataSource.substring(0,1) == "/"){
    System.out.println("trailing forward slash, delete it ");  
    dataSource = dataSource.substring(1);
}

This IF statement isn’t being detected.

Anyone see what I’m doing wrong?

For string comparisons use equals method, as it is more reliable than using == operator (it compares the content while == comnpares the references ) :

Try using equals method :

if(dataSource.substring(0,1).equals("/")){
