Method

inttoInteger(String value, int defaultValue)
Parse a string to an integer value, using a given default on fail 
int ret = defaultValue;
try {
    ret = Integer.parseInt(value);
} catch (NumberFormatException e) {
return ret;
inttoInteger(String value, int defaultValue)
to Integer 
int valueAsInt = 0;
try {
    valueAsInt = Integer.parseInt(value);
} catch (NumberFormatException e) {
    return defaultValue;
return valueAsInt;
IntegertoInteger(String value, Integer defValue)
Parse the given String value as an integer. 
try {
    return Integer.parseInt(value);
} catch (NumberFormatException e) {
    return defValue;
IntegertoInteger(String[] s)
to Integer 
if (s == null || s.length == 0)
    return null;
Integer result = null;
try {
    result = Integer.valueOf(s[0]);
} catch (NumberFormatException e) {
return result;
...
Integer[]toInteger(String[] source)
to Integer 
Integer[] result = new Integer[source.length];
for (int i = 0; i < source.length; i++) {
    Integer v = Integer.getInteger(source[i]);
    if (v != null) {
        result[i] = v;
return result;
...
IntegertoInteger(StringBuilder value)
to Integer 
return Integer.parseInt(value.toString());
int[]toIntegerArray(byte[] input, int offset, int len)
to Integer Array 
assert len % 4 == 0 : "Must be a multiple of 4 bytes";
int[] result = new int[len / 4];
toIntegerArray(input, offset, len, result, 0);
return result;
int[]toIntegerArray(double[] doubles)
Converts an array of double values into an array of integer values by casting them. 
int[] ints = new int[doubles.length];
for (int i = 0; i < doubles.length; i++) {
    ints[i] = (int) doubles[i];
return ints;
Integer[]toIntegerArray(final int[] array)
Converts the primitive int array into an Integer wrapper object array. 
final Integer[] integerArray = new Integer[array == null ? 0 : array.length];
if (array != null) {
    for (int index = 0; index < array.length; index++) {
        integerArray[index] = array[index];
return integerArray;
Integer[]toIntegerArray(final int[] ints)
Produces an array of Integer objects from an int[]. 
final Integer[] result = new Integer[ints.length];
for (int i = 0; i < ints.length; i++) {
    result[i] = Integer.valueOf(ints[i]);
return result;
