Parse a String to boolean

Question

How do you parse a String to boolean, isn't like this? I get this inconertible types error, that require boolean
boolean all = (boolean)tokens.nextToken();
Thanks!

Answer 1

What string means true, and what string means false? The string "true" or "false"? In that case, you can simply use the Boolean.valueOf(String) method:
public static Boolean valueOf(String s)
    Returns a Boolean with a value represented by the specified String. The Boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".
    Example: Boolean.valueOf("True") returns true.
    Example: Boolean.valueOf("yes") returns false.
    Parameters:
        s - a string.
    Returns:
        the Boolean value represented by the string.Otherwise, you can use something like:
  boolean b = string.equals("true");or if string can be null to also mean false:
  boolean b = "true".equals(string);
