Java equivalent of PHP's implode(',' , array_filter( array () ))

Question

I often use this piece of code in PHP

$ordine[\'address\'] = implode(\', \', array_filter(array($cliente[\'cap\'], $cliente[\'citta\'], $cliente[\'provincia\'         


        

Answer 1

Use this simple function:

private String my_implode(String spacer, String[] in_array){

    String res = "";

    for (int i = 0 ; i < in_array.length ; i++) {

        if (!res.equals("")) {
            res += spacer;
        }
        res += in_array[i];
    }

    return res;
}

Use:

data_arr = {"d1", "d2", "d3"};
your_imploded_text = my_implode(",", data_arr);
// Output: your_imploded_text = "d1,d2,d3"
