Method

intrange(int unit)
Don't get excited. 
switch (unit) {
case YEARS:
    return Integer.MAX_VALUE;
case MONTHS:
    return 12;
case DAYS:
    return 30;
case HOURS:
...
intrange(int v, int min, int max)
range 
return min(max(v, min), max);
intrange(int value, int min, int max)
range 
if (value < min)
    return min;
if (value > max)
    return max;
return value;
Integer[]range(Integer from, Integer to)
Generate a range between two bounds 
Integer[] result = new Integer[to - from + 1];
for (int i = from; i <= to; i++) {
    result[i - from] = i;
return result;
doublerange(long array[])
range 
return (max(array, array.length) - min(array, array.length));
long[]range(long start, long end)
range 
long[] values = new long[(int) Math.abs(end - start) + 1];
if (end < start) {
    long oldstart = start;
    start = end;
    end = oldstart;
for (long i = start; i <= end; i++) {
    values[(int) (i - start)] = i;
...
booleanrange(String field, int start, int end)
Validate how long a field can be 
if (field == null) {
    return false;
int length = field.length();
if (end >= length) {
    end = length - 1;
return (start >= 0) && (end >= 0) && (start <= end) && (length > 0);
...
String[]range(String input[], int beginIndex, int endIndex)
returns a range of a string table elements as a new string table 
String ret[] = null;
if (input != null) {
    if ((beginIndex >= 0) && (endIndex < input.length) && (beginIndex <= endIndex)) {
        ret = new String[endIndex - beginIndex + 1];
        for (int i = beginIndex; i <= endIndex; i++) {
            ret[i - beginIndex] = input[i];
return ret;
Stringrange(String second, String first)
range 
try {
    int from = Integer.parseInt(first);
    int to = Integer.parseInt(second);
    if (from > to) {
        int temp = from;
        from = to;
        to = temp;
    } else if (from == to)
...
Trange(T val, T min, T max)
Clips a number so it never goes above its max number or below its minimum number. 
if (val.compareTo(min) < 0)
    return min;
else if (val.compareTo(max) > 0)
    return max;
else
    return val;
