[Solved]Java Interpret Code 1 Int Arr 9 1 0 8 5 7 8 2 Int Sum 0 Int 1 Arrlength 0 2 Sum Arr System Q37063746

Java. How do I interpret this code?

1.

int[] arr = { 9, -1, 0, 8, -5, 7, 8, 2 };

int sum = 0;

for (int i = 1; i < arr.length 0; i *= 2){

   sum += i*arr[i];

}

System.out.printf(“%d%n”, sum);

2.

// assume the file opens successfully

try (PrintWriter fileOut =

   new PrintWriter(“fishing.txt”)){

   for (int i = 0; i < 3; i++)

      fileOut.println(“a fish “+ i +

           ” in the hand”);

   fileOut.close();

  

} catch (FileNotFoundException ex) {

   System.out.println(“File not found. ” + “Check the file name!”);

   System.exit(0);

}

3.

public classFinalExample {

   publicstatic void main(String[] args)

   {

     double x = 10;

     double y = 13;

     double z = -4.4;

     

     System.out.printf(“%.1f%n”, x);

     System.out.printf(“%.1f%n”, y);

     System.out.printf(“%.1f%n”, z);

     z = f(x, y);

     System.out.printf(“%.3f%n”, z);

   }

   publicstatic double f(double x,

                         double y {

     x += (2*y);

     y -= 6;

     return (y – x);

  }  

}
