A Color class has a method getColorName that returns a string corresponding to the common name for the color, e.g., yellow, blue

, white, etc. If there is no common name associated with the color, null is returned. The class, AlphaChannelColor-- a subclass of Color-- has an integer instance variable, alpha, containing the alpha channel value, representing the degree of transparency of the color. Write the method getColorName of AlphaChannelColor, that overrides the method in the Color class. AlphaChannelColor's getColorName should return the name of the color (obtained from the getColorName method of Color) prefixed with the word 'opaque' if the alpha value is less than 100, 'semi-transparent' if the alpha value is otherwise less than 200, and 'transparent' otherwise (separate the prefix from the color name by a blank). If the color has no name, the method should return "opaque color", "semi-transparent color", or "transparent color", according the the same alpha values as above.

Answer:

public String getColorName() {

String name = super.getColorName();

if (name == null) name = "color";

if (alpha < 100)

return "opaque " + name;

else if (alpha < 200)

return "semi-transparent " + name;

return "transparent " + name;

}

Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the elemen
Xelga [282]

Answer:

The JAVA program to implement for loop for given scenario is shown below.

public class MyProgram {

   public static void main(String args[]) {    

     int len = 5;

     int[] lowerScores = new int[len];      

     lowerScores[0] = 5;

     lowerScores[1] = 0;

     lowerScores[2] = 2;

     lowerScores[3] = -3;      

     System.out.println("The original elements of array are ");

     for(int i=0; i<len; i++)

     {

         System.out.print(lowerScores[i]+" ");

     }      

     System.out.println();

     System.out.println("The modified elements of array are ");

     for(int i=0; i<len; i++)

     {

         // if element is 0 or negative, 0 is assigned to this index

         if(lowerScores[i] <= 0)

           lowerScores[i] = 0;

       // 1 is subtracted from every non zero and positive element

         else

           lowerScores[i] = lowerScores[i] - 1;

           

       System.out.print(lowerScores[i]+" ");

     }

   }

}

OUTPUT

The original elements of array are  

5 0 2 -3 0  

The modified elements of array are  

4 0 1 0 0

Explanation:

The integer array is declared as shown.

int[] lowerScores = new int[len];

The length of the array is given by integer variable len. As per the question, we have taken four elements and size of 5 for the given array.

int len = 5;

The elements of the array are initialized inside the program with the elements given in the question.

lowerScores[0] = 5;

      lowerScores[1] = 0;

The values of the array can be changed to test the program. Also, the size of the array can be changed for testing.

As per the given scenario, if the element is greater than zero, 1 is subtracted from this element. For elements less than or equal to zero, that particular element is assigned the value of 0.

The given program implements if else statement inside for loop for this purpose.

for(int i=0; i<len; i++)

     {

         // if element is 0 or negative, 0 is assigned to this index

         if(lowerScores[i] <= 0)

           lowerScores[i] = 0;

       // 1 is subtracted from every non zero and positive element

         else

           lowerScores[i] = lowerScores[i] - 1;

     }
