Method Detail

toString

public static java.lang.String toString(java.lang.Object o)

Same as object.toString() except for arrays, which come out as "{a[1],a[2],...}". The object may be null, which converts to "null".

intValue

public static int intValue(java.lang.String s,
                           int dfault)

Returns the decimal integer value represented by the String, or the given default if the string is null or its format is bad.

upTo

public static java.lang.String upTo(java.lang.String subject,
                                    java.lang.String delimiter)

Returns a prefix of subject, up to the first occurrence of the delimiter string, or the entire subject if the delimiter is not found.

upToLast

public static java.lang.String upToLast(java.lang.String subject,
                                        java.lang.String delimiter)

Returns a prefix of subject, up to the last occurrence of the delimiter string, or the entire subject if the delimiter is not found.

after

public static java.lang.String after(java.lang.String subject,
                                     java.lang.String delimiter)

Returns a suffix of the subject, starting just after the first occurrence of the delimiter string. If the delimiter is not found, returns the entire subject without copying it.

afterLast

public static java.lang.String afterLast(java.lang.String subject,
                                         java.lang.String delimiter)

Returns a suffix of the subject, starting just after the last occurrence of the delimiter string. If the delimiter is not found, returns the entire subject without copying it.

padRight

public static java.lang.String padRight(java.lang.String s,
                                        int width,
                                        char c)

Pad a string on the right to the specified width in characters, using the specified pad character and returning the string with added padding. Never truncate.

padLeft

public static java.lang.String padLeft(java.lang.String s,
                                       int width,
                                       char c)

Substitute a new value in place of all occurrences one substring within a subject string.

readAll

public static java.lang.String readAll(java.io.InputStream ins)
                                throws java.io.IOException

Read all remaining input from the InputStream through the default character encoding, and return it as a String.
