.. Write a method called findNums that takes a two-dimension array of integers as a parameter and returns the number of times a two-digit number appears in the array. For example, if the array (as created by the program below) is

10 45 3 8

2 42

3 21 44

The value returned would be 5 (there are 5 two-digit numbers in the array)

public class Question2 {

public static void main(String args[]){

int arr[][] = {{10, 45, 3, 8}, {2, 42}, {3, 21, 44}};

System.out.println(“The number of two digit numbers is “+findNums(arr));

} //main

-java code

Expert Solution

Java Code

public class Question2
{
public static int findNums(int a[][]) //function for finding wheather the number is two digit numbers or not
{
int num=0;
for (int i = 0; i < a.length; ++i) //retriving the elements of the array
{
for(int j = 0; j < a[i].length; ++j)
{
if (a[i][j]>=10 && a[i][j]<=99) //checking the number is two digit numbers or not
{
num++; //counting
}
}

}
return num; //return the number of two digit
}

public static void main(String args[]){

int arr[][] = {{10, 45, 3, 8}, {2, 42}, {3, 21, 44}};

System.out.println("The number of two digit numbers is "+findNums(arr)); //function call

}
}

I hope the answer is clear and satisfactory . If you have any doubts feel free to ask in the comment section. Please give a thumbs up.

use java for : 1. Write a method called indexOfMax that takes an array of integers and returns the index of the largest element. 2. The Sieve of Eratosthenes is “a simple, ancient algorithm for finding all prime numbers up to any given limit” (https://en.wikipedia. org/wiki/Sieve_of_Eratosthenes).Write a method called sieve that takes an integer parameter, n, and returns a boolean array that indicates, for each number from 0 to n -1, whether the number is prime.

Write a method, remove, that takes three parameters: an array of integers, the length of the array, and an integer called removeItem.

Java programming:Write a method, remove, that takes three parameters: an array of integers, the length of the array, and an integer called removeItem. The method should find and delete the first occurrence of removeItem in the array. If the value does not exist or the array is empty, output an appropriate message. (Note that after deleting the element, the array size is reduced by 1.) You may assume that the array is unsorted.Now re-do this exercise and name it ExInsertionSort....

In an application write a method filterStack that takes a stack of integers as a parameter and filters its elements (in a new Stack) in a way that places the even elements at the bottom and the odd ones at the top. The original stack should remain unchanged. You should use a queue (only one queue) as a temporary storage. Use stack and queue operations only to solve this problem. No need to write the main method. For example, if...

[15 marks] (GetPositiveNumbers.java) Write a method that receives an array of integers as a parameter. The method finds and returns an array which contains the positive numbers. For example, if the method receives an array with the following elements: 0 3 -1 2 5 1 -5 2 -2 0 the method should return an array with the following elements: 3 2 5 1 2 In the main method, randomly generate an array of 10 random integers between -5 and 5,...

C++ Write a function called linearSearch that takes an array as a parameter and search for a specific value inside this parameter. The function returns the frequency of a specific value in the array. In the main function: 1. Define an array called salaries of length 5. 2. Initialize the array by asking the user to input the values of its elements. 3. Define a variable called key and ask the user to enter a value for this variable. 4....

Write a static method called "evaluate" that takes a string as a parameter

In Java language Write a static method called "evaluate" that takes a string as a parameter. The string will contain a postfix expression, consisting only of integer operands and the arithmetic operators +, -, *, and / (representing addition, subtraction, multiplication, and division respectively). All operations should be performed as integer operations. You may assume that the input string contains a properly-formed postfix expression. The method should return the integer that the expression evaluates to. The method MUST use a stack...

Write a method that takes an integer array as its parameter and sorts the contents of the array in ascending order using the Insertion Sort algorithm. Call this method after the original array and other stats have been displayed. Once the array has been sorted by your method, display its contents to the screen in the same manner as the original array was displayed.
