Write a function solution that returns an arbitrary integer which is greater than n.
Aleksandr-060686 [28]

Answer:

   public static int greaterThanInt(int n){

       return n+10;

   }

Explanation:

This is a very simple method in Java. it will accept an argument which is an integer n and return n+10 since the question requires that an arbitrary integer greater than n be returned adding any int value to n will make it greater than n.

A complete java program calling the method is given below:

<em>import java.util.Scanner;</em>

<em>public class ANot {</em>

<em>    public static void main(String[] args) {</em>

<em>        Scanner in = new Scanner(System.in);</em>

<em>        System.out.println("Please enter an integer");</em>

<em>        int n = in.nextInt();</em>

<em>        int greaterInt = greaterThanInt(n);</em>

<em>        System.out.println("You entered "+n+", "+greaterInt+" is larger than it");</em>

<em>    }</em>

<em>    public static int greaterThanInt(int n){</em>

<em>        return n+10;</em>

<em>    }</em>

<em>}</em>
