A two-dimensional array can have elements of ________ data type(s).

Computers and Technology

Igoryamba2 years ago

The answer is "One". The number of dimensions is the representation of the array and has nothing to do with the data types the array can contain.

All array's can only hold one data type, the type it was initialized with.

Write a program FindDuplicate.java that reads n integer arguments from the command line into an integer array of length n, where
kozerog [31]

Answer:

  1. public class FindDuplicate{
  2.    public static void main(String[] args) {
  3.        Scanner input = new Scanner(System.in);
  4.        int n = 5;
  5.        int arr[] = new int[n];
  6.        for(int i=0; i < arr.length; i++){
  7.            int inputNum = input.nextInt();
  8.            if(inputNum >=1 && inputNum <=n) {
  9.                arr[i] = inputNum;
  10.            }
  11.        }
  12.        for(int j =0; j < arr.length; j++){
  13.            for(int k = 0; k < arr.length; k++){
  14.                if(j == k){
  15.                    continue;
  16.                }else{
  17.                    if(arr[j] == arr[k]){
  18.                        System.out.println("True");
  19.                        return;
  20.                    }
  21.                }
  22.            }
  23.        }
  24.        System.out.println("False");
  25.    }
  26. }

Explanation:

Firstly, create a Scanner object to get user input (Line 4).

Next, create an array with n-size (Line 7) and then create a for-loop to get user repeatedly enter an integer and assign the input value to the array (Line 9 - 14).

Next, create a double layer for-loop to check the each element in the array against the other elements to see if there is any duplication detected and display "True" (Line 21 - 22). If duplication is found the program will display True and terminate the whole program using return (Line 23). The condition set in Line 18 is to ensure the comparison is not between the same element.

If all the elements in the array are unique the if block (Line 21 - 23) won't run and it will proceed to Line 28 to display message "False".

given:an int variable k,an int array currentMembers that has been declared and initialized,an int variable memberID that has bee
Oksi-84 [34.3K]

Answer:

// The code segment is written in C++ programming language

// The code segment goes as follows

for (k = 0; k < nMembers; k++)

{

//check if memberID can be found in currentMembers

if (currentMembers[k] == memberID){

// If yes,

// assigns true to isAMember

isAMember = true;

k = nMembers;

}

else{

isAMember = false;

// If no

// assigns false to isAMember

}

}

// End of segment:

The following assumption were made in the code segment above.

There exists

1. An already declared and initialised int array currentMembers.

2. An already initialised int variable memberID

Line 3 initiates a loop to scan through the array

Line 6 checks for the condition below

If current element of array equals memberID then

It assigns true to isAMember and nMembers to k

Else

It assigns false to isAMember
