Multiplying arrays of values ​​in Java?

Question

JavaScript

Good afternoon!
There is some need to obtain a multiplied array of strings.
Type:
array1 = april, may, june
array2 = 1992,1993,1994
array3 = Moscow, St. Petersburg
It is necessary to get all variants of the type:
Moscow, April, 1992
Moscow, April, 1993
Moscow, April, 1994
Moscow, May, 1992
... ..
SPb, June, 1994
Compiled the following code in Java, with simple loops:
for (var i = 0; i < array1.length; i++) {
if (array1[i] != "") {
for (var t= 0; t< array2.length; t++) {
if (array2[t] != "") {
for (var q=0; q< array3.length; q++) {
if (array3[q] != "") {
for (var z=0; z< Array4.length; z++) {
if (array4List[z] != "") {
listResult = listResult + array1[i].trim () + " " + array2[t] + " "+array3[q]+"\r\n";
}
}
}
}}}}}}
I would like to know if there are any other ways besides using such a number of loops? (As an upcoming task, I will need to multiply about 8 such arrays)
There is a solution in other languages, I'll try to figure it out.

Answer 1

multiply, java...
You need to make combinations in Javascript.

Answer 2

I think you are confusing array multiplication with string concatenation. And also confuse Java and JavaScript - they are two different languages ​​with significant differences.
And yes, arrays will have to be bypassed with at least some iterator.
