QN030. Write a program to search specific number within array elements and print the number of repetition.

---

1. Objective

To earch specific number within array elements and print the number of repetition.

2. Theory

In this program we use for loop to travel through all the elements of array and apply if statement to find the matching value.

3. Source Code

import java.util.Scanner;
public class Main{
public static void main(String[] args){
int count=0, n;
Scanner input = new Scanner(System.in);
System.out.print("Enter a number to search: ");
n = input.nextInt();
int arrayVar[] = {2, 6, 17, 9, 15, 9, 4, 7, 9, 2, 9};
for(int i = 0; i < arrayVar.length; i++){
if(n == arrayVar[i])
count++;
}
if(count!=0)
System.out.println(n + " is in array and repeated " + count + " times.");
else
System.out.println(n + " is not in array.");
}
}


4. Output

Enter a number to search: 17
17 is in index 3

5. Conclusion

In this way, I would like to conclude that, we can search any number in given array using this program.
