Answer:
Hi LizBiz! The answer is Ctrl key on Windows, or Command key for Mac.
Explanation:
The Ctrl (Windows) key or equivalent Command key on Mac has a special purpose which allows special operations to be performed when combined with another action, such as clicking on multiple pictures or files for selection.
Answer:
The program to this question can be given as follows:
Program:
//class
public class factorial //defining class
{
//method fact
public static long fact(int x1) //defining method fact
{
//conditional statement
if (x1 <= 1) //if block checks parameter value less then equal to 1
{
return 1; //return value
}
else //else part
{
return (fact(x1 - 1) * (long) x1); //return factors using recursive function
}
}
//method main
public static void main(String[] args) //defining main method
{
long data=fact(5);//defining variable that holds function value
System.out.println("Factorial is: "+data); //print value
}
}
Output:
Factorial is: 120
Explanation:
In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.
- If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.
- In else part, it uses a recursive function to calculate factorial of a number and return its value.
- Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.
Answer:
The following code are:
public void dissolve() {
setRed(getRed()+1);
setGreen(getGreen()+1);
setBlue(getBlue()+1);
alpha+=1;
}
Explanation:
Here, we define the void type function "dissolve()" inside it, we set three function i.e, "setRed()", "setGreen()", "setBlue()" and then we increment the variable "alpha" by 1.
Inside those three mutators method we set three accessor methods i.e, "getRed()", "getGreen()" , "getBlue()" and increment these accessor by 1.
The values will not be returned by the mutator functions, the accessor will be returned the values.
