I've got an if statemtent that returns true when whitespace is found at an indexed point in a string.

if(Character.isWhitespace(c.charAt(0)))
{
return true
}

I want to do the same kind of thing if a < is found. Is there a similar way to do this?

Any help would be great.

(Toggle Plain Text)

c.charAt(0) == '<'

I believe that is what you are looking for.

If you are searching a string for a particular character, you should use the indexOf methods of String instead.

Additionally, you can condense the code fragment you provided to one line:

(Toggle Plain Text)

return Character.isWhitespace(c.charAt(0));

Lastly, please use code tags when posting in the future.

You could test string.indexOf('<')!=-1, or you could just use the contains method:

(Toggle Plain Text)

class bleh
{
  public static void main(String [] args)
  {
    String s = "something";
    String t = "something<else";
    if(s.contains("<"))
      System.out.println("\"" + s + "\" has a <");
    if(t.contains("<"))
      System.out.println("\"" + t + "\" has a <");

  }
}

output:

(Toggle Plain Text)

jimmy@vera ~/code/randomStuff $ java bleh
"something<else" has a <

thanks for the replys. I need to find html tags in a string so the

(Toggle Plain Text)

c.charAt(0) == '<'

method should be sufficient.
