  3.    public static void main(String[] args) {
  4.    int first, second, third, fourth,total;
  5.    double decimalOne, decimalTwo, decimalTotal;

  7.    public static void getData(int first, int second, int third, int fourth, double decimalOne, double decimalTwo){
  8.        System.out.println("Enter the Values");
  9.        Scanner in = new Scanner(System.in);
  10.        first=in.nextInt();
  11.        second=in.nextInt();
  12.        third=in.nextInt();
  13.        fourth=in.nextInt();
  14.        decimalOne = in.nextDouble();
  15.        decimalTwo = in.nextDouble();
  16.    }
  17.    public static int computeTotal(int first, int second, int third){
  18.        return first+second+third;
  19.    }
  20.    public static int computeTotal(int first, int second, int third, int fourth){
  21.        return first+second+third+fourth;
  22.    }
  23.   public static double computeTotal(double decimalOne, double decimalTwo){
  24.        return decimalOne+decimalTwo;
  25.    }

  27.        System.out.println("Number one, two and three are: "+first+" "+second+" "+third);
  28.    }
  29.    public static void printAll( int first, int second, int third, int fourth){
  30.        System.out.println("Number one, two and three and four are: "+first+" "+second+

  32.    }
  33.   public static void printAll( int first, int second, int third, int fourth, int fifth){
  34.        System.out.println("Number one, two and three and four are: "+first+" "+second+
  35.                " "+third+" "+fourth+" "+fifth);
  36.    }
  37.    public static void printAll( double first, double second, double third){
  38.        System.out.println("Number one, two and three and four are: "+first+" "+second+
  39.                " "+third);
  40.    }
  41. }

Explanation:

This solution is provided in Java:

All the variable declarations are done in the main method (lines 3-6)

Eight methods as specified in the question are created (Lines 7, 17, 20, 23, 26, 29, 33 and 37).

Observe the concept of Method Overloading (i.e. methods with same name and return types but different parameter list)

A method variable a class variable with the same name. a) acquiesces to b) destroys c) overrides d) alters
arlik [135]

Answer:

Option(c) is the correct answer for the given question.

Explanation:

The method variable overrides the class variable name with same name The method variable overrides of the class variable name .

Following are the example in java language

public class Main

{

int b=90; // class varaible or instance varaible

void sum()

{

   int b=34; // method having same name as class varaible name

   b=b+10;

   System.out.println(b); // display b

}

public static void main(String[] args)  // main method

{

 Main ob=new Main(); // craete object

 ob.sum(); // calling method sum

}

}

Output:

44

In this we declared a variable 'b' as int type in class and override this variable in sum() function it means same variable name is declared in function sum() .

acquiesces ,destroys,alters are the wrong for the given question.

So overrides is the correct answer
