Question

I need a java flowchart for the following code:

import java.util.*;
public class Main
{
   public static void main(String[] args) {
   Scanner sc=new Scanner(System.in);
  
       System.out.print("Enter the input size: ");
       int n=sc.nextInt();
       int arr[]=new int[n];
       System.out.print("Enter the sequence: ");
       for(int i=0;i<n;i++)
       arr[i]=sc.nextInt();
       if(isConsecutiveFour(arr))
       {
       System.out.print("yes the array contain consecutive number:");
       for(int i=0;i<n;i++)
       System.out.print(arr[i]+" ");
       }
       else
       System.out.print("Not a consecutive sequence");
      
      
      
   }
   public static boolean isConsecutiveFour(int[] values){
   int c=0;
       //consecutive seq :- 1 2 3 4 5 whose dffirence is 1
      
       for(int i=0;i<values.length-1;i++)
       {
       if(values[i]+1==values[i+1])
       c++;
       }
       if(c+1==values.length)
       return true;
       else
       return false;

      
   }
}

Answer 1

At first this program import the complete package of java util.

After that main class is created in which main method is created (public static void main) then make the object of scanner class which is used to take the input from user.

After that program takes the input from user using System.out.println command and store the value in N variable.

After that arr[] variable type of int data type created and assign the value of N variable into this arr[] variable.

After that for loop is created which is started from i=0 and repeat till the i less n and increment in i variable then these value stores in the arr[] by using sc.nextInt() method.

After that if condition start which check the values stored in array is consecutive till four or not and incremented the array if array values in continous form then it will print yes array contain the consecutive number otherwise print the else condition.

After that is boolean Consecutive method is created which is public with int value variable parameter then C variable is declared and defined with 0 which is int data type.

After that another for loop is created for checking the values are consecutive or not or we can say that the difference between values is 1 or not then for loop is start from i=0 and continues till i<values.length-1 and then increment the i.

After that if condition is created which checks value[i]+1 is equal to values[i+1] or not.If yes then increment c variable by 1 and nested if condition is start which is created after above if condition and checks c+1 ==value.length or not if it yes then its return true otherwise else condition will execute which returns false
