Method Detail

duplicate

public static java.lang.Object duplicate(java.lang.Object o)

capitalize

public static java.lang.String capitalize(java.lang.String string)

Capitalizes the first letter of a string. For example, "test" becomes "Test".

Parameters:

string - String to capitalize

Returns:

a new string with the first letter capitalized.

readFile

public static java.lang.String readFile(java.lang.String fileName)

Reads the contents of a file (generally text or html) into a String using a StringBuffer. Returns null if the file cannot be read. The path is read relatively with respect to this class, using getResourceAsStream(), so the semantic rules for how that file loader works apply.

Parameters:

fileName - Filename, including path, of the file to read.

Returns:

a new string containing the contents of the file.

encodeUrl

public static java.lang.String encodeUrl(java.lang.String url)

Removes illegal characters from URLs. Specifically, this method removes spaces from a URL and replaces them with a plus character, as is the convention with CGIs.

Parameters:

url - String to convert to a legal URL

Returns:

the new string with illegal characters escaped.
