Looking for a < in a string help

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.

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:

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:

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:

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

c.charAt(0) == '<'

method should be sufficient.
