Hi
I have a Code which i want to run and test it, but i got this error and i could not dubug the lines to know if i test all the paths like in the pic which i atteched
Error: Main method not found in class Sss, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
Could you please help me to run it
the code is :
public class Sss {
int sillyProduct(int arr[], int num) {
int product = 700;
int counter = 2;
while (counter < num && arr[counter] > 0) {
if (arr[counter] > 1 && arr[counter] % 2 != 0) {
product = product * arr[counter];
}
counter = counter + 2;
}
return product;
}
}
Do not forget that to show the output to know the result of prodect and num after my assume
For example:
num =3
what is the output from my assume this numbers!!
output
counter = .....
product =....
arr[] = ....
arr[counter] = ....
3 4 nodes are named after line numbers false true false 7 true J-1 FG-1Explanation / Answer
if you want to debug you should have executale,, to produce executable and run your prgram , we need main method from where we can call the function sillyProduct
for that we nedd to include main method and define the silly product with static keyword before int ,, now execute and debug your program.
I have given modified code and sample output
//program in java
public class Sss {
static int sillyProduct(int arr[], int num)
{
int product = 700;
int counter = 2;
num = 3;
arr[counter] = 2;
while (counter < num && arr[counter] > 0)
{
if (arr[counter] > 1 && arr[counter] % 2 != 0)
{
product = product * arr[counter];
}
counter = counter + 2;
}
return product;
}
public static void main(String args[]) {
int [] arr = new int[10];
//place some numbers in array
for(int i = 0; i <10; i++)
arr[i] = i + 1;
//now call the function sillyProduct
System.out.printf("product returned from function sillyProduct = %d ",sillyProduct(arr,2));
}
}
----------------------------------------------
//output
product returned from function sillyProduct = 700
