1) Above is a simple web browser coding
2) Paste your code.

.how to get rid of this code?

The font of your image is too small, can you copy and paste here what you want us to see?

How can we recommend a change to your code if you don't show it?
Obviously your parser and formatter is not working properly.

java can't read Javascripts. The code that is showing you the program is a javascript.

[hamzamuradkhanh]

so how to get rid of this code,what i should do now?

[NormR1]

how to get rid of this code

Read the text of the page and remove the parts that your display engine doesn't know how to format before giving it the text.

Please edit your code and wrap it in code tags. See [code] icon above input box.

[hamzamuradkhanh]

how can i rendered javascript code into my simple browser?

[NormR1]

Find a package to do the rendering. But, I doubt there is one.

[teo236]

the best way to do a web browser is using another language instead of Java. It would be a whole project to execute javascripts.

[NormR1]

using another language instead of Java

@teo 236 Can you explain what the problem is with doing it in Java?

[teo236]

it will be very confusing trying to execute javascripts in java. maybe there is a better language for this kind of projects. If hamzamuradkhanh wants to execute javascripts with java, it's possible but would probably be very slow execution. I researched and found this page http://www.mozilla.org/rhino/ if you are interested.

[NormR1]

Did you notice this in the rhino doc: written entirely in Java

[teo236]

have you tried to use it? it's confusing.
