Question
I would like to get the output of this code and the explanation of it. I need a very detailed explanation
-Java code
5) Write down the output that the code below generates when executed by the command "java prog 3 4 5 -6 public class prog{ public static int fnc1(int0 a, int b) int i, j 0; for (i 0; ikb i +2) return j; public static void main (Stringo args)( int0 y new int[Integer.parselnt(args[0])l; for (int i 0; ikinteger.parselnt(args[0]); i++) ylil Integer. parselnt(argsli+1]); System.out.print(fnc1(y, Integer.parselnt(args[0])) OutputExplanation / Answer
// Prog.java
public class Prog
{
// method fnc1 which iterates over the array and determines the
// sum of elements of array at even index
public static int fnc1(int[] a, int b)
{
// j stores the sum of elements of array
int i,j = 0;
// iterate over the array at even indexes
for (i = 0; i < b; i=i+2 )
{
// add the index value to j
j = j + a[i];
}
// at i = 0, j = 0 + a[0] => 0 + 4 = 4
// then i = 2, j = 4 + a[2] => 4 + -6 = -2
// return the value of j which is -2
return j;
}
public static void main(String[] args)
{
// created an array y of data type integers
// with size equal to first argument passed while running the program
// in this case args[0] = 3
int[] y = new int[Integer.parseInt(args[0])];
// iterate over the number of elements in the array
// elemnts of array y will be 4,5 and -6
for(int i =0;i< Integer.parseInt(args[0]);i++)
y[i] = Integer.parseInt(args[i+1]); // the command line arguments from 1st index to the last index are the elementss of array
// pass the array y to the method with input argumnets
// the array and the size of array
System.out.print(fnc1(y,Integer.parseInt(args[0]))+";");
}output: -2;
}
/*
output: -2;
