In many languages (including Java), you can form a color by specifying certain amounts of red, green, and blue, with each color's amount ranging from 0% to 100%. For example, to specify purple, you could use this code
rgb(100%, 60%, 100%)
The rgb stands for red, green, and blue. With 100% for red and blue, the resulting color is purple. In the following Rgb and RgbDriver class skeletons, replace the <insert...> lines with appropriate code such that the program operates properly. More specifically:
- In the Rgb class, provide a method definition for the setRed method such that setRed can be called as part of a method-call chain.
- In the RgbDriver class, provide a single statement that chains calls to the setRed, setGreen, setBlue, and display For your method-call arguments, pass 100 to setRed, 60 to setGreen, and 100 to setBlue. With those argument values, your method-call-chaining statement should print this:
rgb(100%, 60%, 100%)
public class Rgb
{
private int red;
private int green;
private int blue;
<insert setRed method definition here>
public Rgb setGreen(int green)
{
this.green = green;
return this;
} // end setGreen
public Rgb setBlue(int blue)
{
this.blue = blue;
return this;
} // end setBlue
public void display()
{
System.out.printf("rgb(%d%%, %d%%, %d%%)n",
this.red, this.green, this.blue);
} // end display
} // end Rgb class
public class RgbDriver
{
public static void main(String[] args)
{
Rgb rgb = new Rgb();
<insert chained method calls here>
}
} // end RgbDriver class

Answer:
I write the method named setRed(int), that set the value of red, and return the object itself.
And in main method i write the method chaining, like this,
rgb.setRed(100).setGreen(60).setBlue(100).display();
This is work properly, you can see, i provide the source code and the output in explanation.
If you have any queries, comment it.
Step-by-step explanation
Source Code:
public class RgbDriver
{
public static void main(String[] args)
{
Rgb rgb = new Rgb();
rgb.setRed(100).setGreen(60).setBlue(100).display();
}
} // end RgbDriver class
public class Rgb
{
private int red;
private int green;
private int blue;
public Rgb setRed(int red)
{
this.red = red;
return this;
} // end setRed
public Rgb setGreen(int green)
{
this.green = green;
return this;
} // end setGreen
public Rgb setBlue(int blue)
{
this.blue = blue;
return this;
} // end setBlue
public void display()
{
System.out.printf("rgb(%d%%, %d%%, %d%%)\n",
this.red, this.green, this.blue);
} // end display
} // end Rgb class
OUTPUT:
PFA
