1. Suppose, you are given the following Java Code. class Student{ protected String var "Student"; class RegisteredStudent extends Student{ private String var = "RegisteredStudent"; public void randomFunction () { String var = "Inside Function"; System.out.println ("Normal var System.out.println ("this.var = System.out.println ("super.var + var) ; + this.var); + super.var); If an object of RegisteredStudent is created, and randomFunction() is called, what will be the output, shown to the console ? (Write full output)
JAVA CODE: check output
Write code that prints: countNum ... 21 Print a newline after each number. Ex: If the input is: 3 the output is: 3 2 1 1 import java.util.Scanner; 3 public class ForLoops { UAWN HOUх и блашин 2 ST 4 5 6 7 8 9 10 11 12 13 14 15 } public static void main (String [] args) { int countNum; int i; Scanner input = new Scanner(System.in); input.nextInt(); countNum = for * Your code goes here *) { System.out.println(i); } }
