Answer:
Explanation:
1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).
2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.
3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.
4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.

Following are the code in java to reverse any string without using reverse function.
import java.util.*; // import package
class Main // class
{
public static void main(String args[]) // main class in java
{
String s, r = ""; // string variable
Scanner out = new Scanner(System.in); // scanner classes to take input
System.out.println("Enter a string to reverse");
s = out.nextLine(); // input string
int l1 = s.length(); // finding length of string
l1=l1-1;
for ( int i = l1 ; i >= 0 ; i-- ) // for loop to reverse any string
{
r = r + s.charAt(i);
}
System.out.println(" The Reverse String is: "+r); // print reverse string
}
}
Explanation:
firstly we input any string ,finding the length of that string then after that iterating over the loop by using for loop and last display that reverse string
output
Enter a string to reverse
san ran
The Reverse String is: nar nas
