Answer to Question #186651 in Java | JSP | JSF for Syed kaif ali

Question

Create a class name FunWithArrays and create the following methods:

⦁ consecutiveValueChecker(int arr[]): This method will not allow user to input consecutive values in an array

Input:

3,4,2,1,5,5

Output: 

Cannot input consecutive value please input value other than 5

⦁ calcultesLongestSequence(String arr[]): This method will take a string array and calculate length of values at each index also print the word having the longest length

Answer 1

import java.util.Arrays;
import java.util.Scanner;


public class FunWithArrays {
	/**
	 * This method will not allow user to input consecutive values in an array
	 * @param arr
	 */
	public boolean consecutiveValueChecker(int arr[]) {

		for(int i=0;i<arr.length-1;i++){
			if((arr[i+1]-arr[i])!=1) {				
				System.out.print("\nCannot input consecutive value please input value other than "+arr[i+1]+"\n");
				return false;
			}
		}
		return true;
	}
	/**
	 * This method will take a string array and calculate length of values at each index also print the word having the longest length

		for(int i=0;i<arr.length;i++){

		} 
		System.out.println("\nThe word having the longest length is \""+word+"\"\n");
