Name | ### concat()
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"

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).
Syntax |
    concat(a, b)
Parameters |
a | Object, String[], float[], int[], char[], byte[], or boolean[]: first array to concatenate
b | Object, String[], float[], int[], char[], byte[], or boolean[]: second array to concatenate
Returns | boolean[], byte[], char[], int[], float[], String[], or Object
