Numbers greater than Given Number From Array in Java

Program description:- Write a Java program to find the numbers which are greater than the given number from an array. Take an array and a number, compare the number with each element of the array.

Example1:-
Array = {10, 20, 30, 40, 50}
Number = 30
Numbers greater than given number = 40, 50

Example2:-
Array = {-10, 5, 0, -9, 18, 27, -36}
Number = 5
Numbers greater than given number = 18, 27

Prerequisite:- Array in Java, find length of array in Java

In this program, we will take input value for the array from the end-user, but you can take it explicitly. See:- how to take array input in Java. We will use a method to perform the operation. 

Procedure to develop Java method to find the numbers greater than the given number,
a) Take an array and a number.
b) Traverse through the array.
c) If the element is greater than the given number then display it.

Java Program to Find Numbers Greater than Given Numbers From Array

import java.util.Scanner;

public class ArrayTest {

  public static void main(String[] args) {
    // create Scanner class object to take input
    Scanner scan = new Scanner(System.in);

    // read size of the array
    System.out.print("Enter size of the array: ");
    int n = scan.nextInt();

    // create an int array of size N
    int numbers[] = new int[n];

    // take input for the array
    System.out.println("Enter array elements: ");
    for (int i = 0; i < n; ++i) {
      numbers[i] = scan.nextInt();
    }

    // take number
    System.out.print("Enter number = ");
    int num = scan.nextInt();
    
    // display numbers greater then given number
    System.out.println("Numbers greater then given number = ");
    display(numbers, num);

    // close Scanner
    scan.close();
  }

  // method to display numbers greater than given number
  public static void display(int[] numbers, int num) {
    // traverse through the array
    for (int i : numbers) {
      if(i > num)
      System.out.print(i+" ");
    }
    
  }
}

Output:-

Enter the size of the array: 5
Enter array elements:
10 20 30 40 50
Enter number = 30
Numbers greater than given number =
40 50

Enter the size of the array: 7
Enter array elements:
-10 5 0 -9 18 27 -36
Enter number = 5
Numbers greater than given number =
18 27
