Whendealing with custom objects in Java, sorting a list can be a bit more complex. Thankfully, Java provides theComparatorinterface, which gives us more control over how our lists are sorted. With aComparator, we can define custom sorting rules for our lists. Let’s take a look at an ex...
functionsumArray(arr){returnarr.reduce((accumulator,currentValue)=>accumulator+currentValue,0);}constnumbers=[1,2,3,4,5];console.log(sumArray(numbers)); Output: 15 In this example, we again define a function calledsumArray. Here, we use thereducemethod on the arrayarr. Thereducemethod tak...
} We put in an array an instance of each implementation. Then we are able to run the desired function by using the array index. public class TestCommand { public static void main(String[] args) { Command[] commands = new Command[3]; commands[0] = new ACommandImpl(); commands[1] =...

the array will still be fully populated. The only difference would be that the element at index position 9 would now be zero; this is because every position in an integer array that's created without an element is assigned a value of zero by default....
