Public methods

buildArray

public static String[] buildArray (String... arrays)

Build an array from the provided contents.

The resulting array will be the concatenation of arrays input arrays, in their original order.

Parameters

public static String join (String sep, 
                Object... pieces)

`sep`	`String`: the string separator to delimit the different output segments.
`pieces`	`Object`: A `ERROR(/Collection)` or a varargs `Array` of objects.

Returns
`String`

list

public static  list (T... inputAry)

Convert a varargs list/array to an ERROR(/List). This is useful for building instances of ERROR(/List) by hand. Note that this differs from Arrays.asList(T) in that the returned array is mutable.

Parameters
`inputAry`	`T`: an array, or a varargs list

Returns
	a `ERROR(/List)` instance with the identical contents
