1. public class DemoArray
   
2. {
   
3. public static void main(String[] args)
   
4. {
   
5. 2. On a new line, declare and create an array that can hold four double values
   
6. by typing the following:
   
7. double[] salaries = new double[4];
   
8. 3. One by one, assign four values to the four array elements by typing the
   
9. following:
   
10. salaries[0] = 6.25;
    
11. salaries[1] = 6.55;
    
12. salaries[2] = 10.25;
    
13. salaries[3] = 16.85;
    
14. 4. To confirm that the four values have been assigned, display the salaries one
    
15. by one using the following code:
    
16. System.out.println("Salaries one by one are:");
    
17. System.out.println(salaries[0]);
    
18. System.out.println(salaries[1]);
    
19. System.out.println(salaries[2]);
    
20. System.out.println(salaries[3]);
    
21. 5. Add the two closing curly braces that end the main() method and the
    
22. DemoArray class.
    
23. 6. Save the program as DemoArray.java. Compile and run the program.
    
24. The program’s output appears in Figure 8-2.
