I. is syntactically correct if genderString exists. if genderString, for example, is "Male", then char gender would be the character at index 0 (the first character), meaning 'M'.
II. is incorrect. It is using the comparison operator (==) instead of the assignment operator (=). It is also setting a boolean variable to a String value of 'F'. Boolean values cannot hold string values, and can only hold true & false.
III. is correct if ageString only contains numbers (presumably, it does, as it's called ageString). Integer.parseInt is a function that converts String values to integer values if the string values only contain numerical characters.
The answer in this case should be B. II only.

class Codechef
{
public static void main (String[] args)
{
Stack<Integer> mat=new Stack<Integer>();
mat.add(1);
mat.add(3);
mat.add(6);
System.out.println(mat);
Object [] a=mat.toArray();
for(int i=0;i<a.length;i++)
System.out.println(a[i]);
}
}
Explanation:
An integer type stack st is created;
1,3 and 6 are added to the stack.
printing the contents of the stack.
array a is created form the stack using toArray().
Then printing the array.
Based on the name of the function, it seems that we're supposed to only print the value of quantity to the console.
def show_value(quantity):
print(quantity)
show_value(12)
The first line of code creates the function, the second line of code prints the value of quantity to the console, and the last line of code calls our show_value function with 12 as our argument. I wrote my code in python 3.8. I hope this helps.
