Thank you for being the rare question where you actually provide what language you want your answer in; I approve, and encourage this.
In Java, the following will work.
I made it a bit more versatile to work with others numbers, other than 99, if you so please (if not, just hardcode the 99 in yourself).
// Example list - fill this with numbers yourself.
ArrayList<Integer> nums = new ArrayList<>();
int n = 99;
int count = (int)nums.stream().filter(i -> i == n).count();
System.out.println(n + " occurences.");
Answer:
Hey don't overthink about it .It all depends on your interest like what you would prefer and how much you can afford. I guess it's your life so you should take a decision by yourself.
I hope it helps..
Google is famously known as a search engine and it is being used around the globe. Aside from being a search engine, it also offers other services such as productivity software or google docs, e-mail services like Gmail, cloud storage or the google drive and it also offers social networking services through google plus. Google also has some desktop application for free of use such as google chrome, picasa and instant messaging like hangouts. Their mission statement as for being the most used search engine is "to organize the world's information and make it universally accessible and useful".
Answer:
Reference
Explanation:
The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. Examples for reference type are classes, interfaces, delegates and arrays.
We can pass parameters to the method by reference using <em>ref </em>keyword
It’s mandatory to initialize the variable value before we pass it as an argument to the method in c#
For example,
int x = 10; // Variable need to be initialized
Add(ref x); // method call
If you pass parameters by reference in method definition, any changes made to it affect the other variable in method call.
Here's a sample program:
using System;
namespace ConsoleApplication
{
public class Test
{
public static void Main()
{
int i = 10;
Console.WriteLine("i=" + i);
Add(ref i);
Console.WriteLine("i=" + i);
Console.ReadLine();
}
public static void Add( ref int j)
{
j = j + 10;
Console.WriteLine("j="+j);
}
}
}
Output:
i=10
j=20
i=20
