Given the class 'ReadOnly' with the following behavior: A (protected) integer instance variable named 'val'. A constructor that

accepts an integer and assigns the value of the parameter to the instance variable 'val'. A method name 'getVal' that returns the value of 'val'. Write a subclass named 'ReadWrite' with the following additional behavior: Any necessary constructors. a method named 'setVal' that accepts an integer parameter and assigns it the the 'val' instance variable. a method 'isDirty' that returns true if the setVal method was used to override the value of the 'val' variable.

Answer:

I believe you want a subclass so here it is!

public class ReadWrite extends ReadOnly {

public ReadWrite(int initialValue){

super(initialValue);

}

private boolean modified = false;

public void setVal(int x) {

val = x;

modified = true;

}

public boolean isDirty() {

return modified;

}

}

Explanation:

I might be wrong, just check through it in case

Hope this helped

:)

JulsSmile [24]

Answer:

public class Pyramid {

   public static void main(String[] args) {

             int h = 7;

       System.out.println("Pattern A");

               for(int i = 1; i <= h; ++i)

               {

                   for(int j = 1; j <= i; ++j) {

                       System.out.print("+");

                   }

                   System.out.println();

               }

       System.out.println();

       System.out.println("Pattern B");

               for (int i = 1; i<=h; ++i)

               {

                 for(int j = h; j >=i; --j){

                     System.out.print("+");

                 }

                   System.out.println();

               }

           }

       }

Explanation:

  • The trick in this code is using a nested for loop
  • The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
  • The inner for loop which prints the (+) sign runs from j = 0 to j<=i
  • It prints the + using the print() function and not println()
  • In the pattern B the loop is reversed to start from  i = height
