1. The following program will not compile. Rewrite it so that it compiles and correctly prints the numbers 0 through 4 on successive lines, and then prints the final value of counter.

public class DemoProgram { public static void main(String[] args) { for (int counter = 0; counter < 5; counter++) { System.out. println(counter); } System.out.print(counter); } }

2. Write a class called DemoClass with an integer field called demoVariable that is not accessible outside the class, and a setter method called setDemoVariable that sets the value of demoVariable and a getter method called getDemoVariable that retrieves the value of demoVariable.
