Name

concat()

Description

Concatenates two arrays. For example, concatenating the array { 1, 2, 3 } and the array { 4, 5, 6 } yields { 1, 2, 3, 4, 5, 6 }. Both parameters must be arrays of the same datatype.

When using an array of objects, the data returned from the function must be cast to the object array's data type. For example: SomeClass[] items = (SomeClass[]) concat(array1, array2).

Examples

String[] sa1 = { "OH", "NY", "CA"};
String[] sa2 = { "KY", "IN", "MA"};
String[] sa3 = concat(sa1, sa2);
println(sa3);
// Prints updated array contents to the console:
// [0] "OH"
// [1] "NY"
// [2] "CA"
// [3] "KY"
// [4] "IN"
// [5] "MA"

Syntax

Parameters

a(boolean[], byte[], char[], int[], float[], String[], Object)first array to concatenate
b(boolean[], byte[], char[], int[], float[], String[], Object)second array to concatenate

Return

boolean[], byte[], char[], int[], float[], String[], or Object
