Identify three different meanings of the word "interface" in Java Programing language.

Mnenie [13.5K]

Answer: Interface methods, interface variables and interface markers.

Explanation:

Interface methods are public and abstract by default.

Interface variables can be declared public, static and final

Marker interfaces are simply empty interfaces without any methods.

Give an example of a function from N to N that is: Hint: try using absolute value, floor, or ceiling for part (b). (a) one-to-on

Naily [24]

Answer:

Let f be a function

a) f(n) = n²

b) f(n) = n/2

c) f(n) = 0

Explanation:

a) f(n) = n²

This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.

Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:

f(a) = f(b) ⇒ a² = b² ⇒ a = b

The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.

b) f(n) = n/2

The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:

f(2n) = [2n/2] = n

The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:

When the value of n=1, then

n/2 = [1/2] = [0.5] = 1

When the value of n=2 then

n/2 = [2/2] = [1] = 1

c) f(n) = 0

The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.

The list method reverse reverses the elements in the list. Define a function named reverse that reverses the elements in its lis

Alisiya [41]

Answer:

public class Reverse {

public static void reverseList(int list [], int n)
{
int[] reversedList = new int[n];
int k = n;
for (int i = 0; i < n; i++) {
reversedList[k - 1] = list[i];
k = k - 1;
}
//printing the reversed list
System.out.println("The Reversed list \n");
for (int j = 0; j < n; j++) {
System.out.println(reversedList[j]);
}
}

Explanation:

Using Java, An array is implemented to hold a list of items

A method reverseList() is created to accept an array as parameter and using a for statement reverses the elements of the array and prints each element of the list

See below a complete code with a main method that calls this method

public class Reverse {

public static void main(String[] args) {

int [] arr = {10, 20, 30, 40, 50};

reverseList(arr, arr.length);

}

public static void reverseList(int list [], int n)

{

int[] reversedList = new int[n];

int k = n;

for (int i = 0; i < n; i++) {

reversedList[k - 1] = list[i];

k = k - 1;

}

//printing the reversed list

System.out.println("The Reversed list \n");

for (int j = 0; j < n; j++) {

System.out.println(reversedList[j]);

}

}
