G. Identify the errors in the given code and rewrite the correct code:
1. public class ArrayExample

{
public static void main(String[] args)
{
int arr = [10, 20, 30, 40];
for (int i = 0; i < arr.size; i++)
{
System.out.Println(arr{i});
}
}
}
Ans. public class ArrayExample
{
public static void main(String args[])
{
int arr[] = {10, 20, 30, 40};
for (int i = 0; i < arr.length; i++)
{
System.out.println(arr[i]);
}
}
}
2. public class ArrayExample

{
public static void main(String args[])
{
int[] numbers = {5, 10, 15, 20};
for (int i = numbers.length; i >= 0; i--)
{
System.out.println(numbers[i]);
}
}
}
Ans. public class ArrayExample
{
public static void main(String args[])
{
int[] numbers = {5, 10, 15, 20};
for (int i = numbers.length-1; i >= 0; i--)
{
System.out.println(numbers[i]);
}
}
}
