Method Summary

Modifier and Type	Method	Description
static <T> boolean	anyValuesInCommon(Collection<T> c1, Collection<T> c2)	Method that can be used to efficiently check if 2 collections share at least one common element.
static <T> Iterator<T>	emptyIterator()
static char[]	getEmptyCharArray()
static int[]	growArrayBy(int[] arr, int more)
static String[]	growArrayBy(String[] arr, int more)
static Object	growArrayBy50Pct(Object arr)
static Object	growArrayToAtLeast(Object arr, int minLen)	Method similar to growArrayBy50Pct(java.lang.Object), but it also ensures that the new size is at least as big as the specified minimum size.
static Object	growArrayToAtMost(Object arr, int maxLen)	Method similar to growArrayBy50Pct(java.lang.Object), but it also ensures that the new size is no bigger than specific maximum size.

Method Details

getEmptyCharArray

public static char[] getEmptyCharArray()

Integer

public static Integer Integer(int i)

singletonIterator

growArrayToAtMost

public static Object growArrayToAtMost(Object arr,
 int maxLen)

Method similar to growArrayBy50Pct(java.lang.Object), but it also ensures that the new size is no bigger than specific maximum size.

growArrayBy
