Constructor Summary

TypeUtil()

Method Summary

static String[]	appendArrayAssign(String[] sa, String s) Returns an array of Strings that results from appending a String to the end of a pre-existing array of Strings.
static int	equalsToCharInArray(char c, char[] ca, int i) Returns index j of ca[] that verifies ca[j] == c, or -1 otherwise.
static int	indexOfStringInArray(String[] sa, String s) Determines the index of a given String in a String array.
static String	intToFormattedString(int i, int n) Returns a String representing the i number with at least n digits.
static String[]	safeArrayAssign(String[] sa, int i, String s) Assigns sa[i] = s, safely so if i>=sa.length it creates a new array with enough free space.
static String[]	stringArrayTrim(String[] a) Trims a String array

Method Detail

stringArrayTrim

public static String[] stringArrayTrim(String[] a)

Trims a String array

appendArrayAssign

public static String[] appendArrayAssign(String[] sa,
                                         String s)

Returns an array of Strings that results from appending a String to the end of a pre-existing array of Strings.

safeArrayAssign

public static String[] safeArrayAssign(String[] sa,
                                       int i,
                                       String s)

Assigns sa[i] = s, safely so if i>=sa.length it creates a new array with enough free space.

equalsToCharInArray

public static int equalsToCharInArray(char c,
                                      char[] ca,
                                      int i)

Returns index j of ca[] that verifies ca[j] == c, or -1 otherwise.

intToFormattedString

public static String intToFormattedString(int i,
                                          int n)

Returns a String representing the i number with at least n digits.

Parameters:

i - integer

n - number of digits

Returns:

formatted string

indexOfStringInArray

public static int indexOfStringInArray(String[] sa,
                                       String s)

Determines the index of a given String in a String array. Does not require the array to be sorted, as in Arrays.binarySearch.
