I am taking input values like this but i am unable to understand how can i use this values for further while loop?

#1

Scanner scan = new Scanner(System.in);
int n = scan.nextInt();

	//System.out.println("Enter the numbers ");
	
	
		for(int i = 1; i<=n ; i++)
		{
		Scanner scan2 = new Scanner(System.in);
		 binaryValues = scan2.nextInt();
		}
#2

Hey @Nitya_Somani
please Send me complete code
Scanner scan2 = new Scanner(System.in); // No need
// Make 1 Scanner obj in a 1 method ya function
Scanner scan = new Scanner(System.in); // use this Scanner

#3

package ChallengePatterns;

import java.util.Scanner;

public class Challenge2 {

public static void main(String[] args)
{
	
	System.out.println("The number of binary numbers to get converted ");
	
	Scanner scan = new Scanner(System.in);
	int n = scan.nextInt();
	
	//System.out.println("Enter the numbers ");
	
	int binaryvalues;
		for(int i = 1; i<=n ; i++)
		{
		Scanner scan2 = new Scanner(System.in);
		 binaryValues = scan2.nextInt();
		}
	
	
	
	// To convert into decimal now
	
	int var = 0 ;
	
	int decimalNo=0;
	
		while( binaryValues > 0 )
			{
				int rem = binaryValues % 10;
				decimalNo = decimalNo +rem *var;
					var=var*2;
					decimalNo = decimalNo /10;
					System.out.println(decimalNo);
					binaryValues++;
	  
	 //prep 
	System.out.println();
	
	
	 
}

}

@Nitya_Somani
correct code:

#5

In this code also it is taking values one by one and then converting it but in question all the 4 values are given together by user and is getting converted together .In this also by scanner one at a time we are taking values

#6

Q. all the 4 values are given together by user and is getting converted together
Answer : you can do it this way. but you don’t know arrays concept.
it’s better to use loop
your for loop execute first Time i=0;
Take input and It will be converted binary to decimal
then execute again i=1;
Take input and It will be converted binary to decimal
The loop will continue. As long as i <4
