[java] AvoidArrayLoops could also check for list copy through iterated List.add()

[wuchiuwong]

Affects PMD Version:
6.22.0

Rule:
AvoidArrayLoops

Description:
It is recommended to have AvoidArrayLoops additionally check the case using that for loop + list.add() to copy a list
Similar to using for loop to manually copy data between two arrays, using for loop + list.add() to manually copy data between two list can also be simplified to Collections.addAll(dest, source)

Code Sample demonstrating the suggestion:
Example 1:

// can also be simplified to <code>Collections.addAll(rawData, dd)
double[] dd = sc.summaryStats();
for (double d : dd) {
	rawData.add(d);
}

Example 2:

// can also be simplified to <code>Collections.addAll(mbeans, beans)
for (int i = 0; i < beans.length; i++) {
	mbeans.add(beans[i]);
}
