Question

I have string value in HTML get web. Stored in varible s as shown below.

<iframe width="560" height="315" src="https://www.youtube.com/embed/ubR8WfwQTkw" frameborder="0" allowfullscreen></iframe>

Problem

I want to change the width value 560 to 250.

I try to use s.replace("560", "250"); but its not working.

Any clues ...how can i change it.

What actually happens ? what's the value of s after executing the previous line ? — Shady Atef

This code works:

String s = "<iframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/ubR8WfwQTkw\" frameborder=\"0\" allowfullscreen></iframe>";
String replace = s.replace("560", "250");
System.out.println(replace);

If you print s you'll see 560 because Strings are immutable in java. If you don't want to declare a new String you could do in this way:

String s = "<iframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/ubR8WfwQTkw\" frameborder=\"0\" allowfullscreen></iframe>";
s = s.replace("560", "250");
System.out.println(s);
