outside the loop

[yan cle]

how can i declare my input on the loop outside the loop and im using array, thanks for who's answering this.

import java.io.*;
public class main{
	public static void main (String[] args) throws IOException{
		BufferedReader cin = new BufferedReader(new InputStreamReader(System.in));
		int input[] = new int[100];
		int loop, valueofy, timesofnumber = 0;

		System.out.print("Number of Loop: ");
		loop = Integer.parseInt(cin.readLine());

		for (int count = 0; count <loop; count++) {
			System.out.print("INDEX [" + count + "]: ");
			input [count] = Integer.parseInt(cin.readLine());	
		}

how can i display it outside the input[count] outside the loop.

Do you mean, how can you display the loop variable "count" after the loop finishes? You can't, not given the code you posted. But when the loop finishes you know that its value is equal to the value of "loop". You could display that.

Or you could just declare the variable outside the loop.

Your class name 'main' should begin with an upper case letter. Variables should be declared separately. Use Scanner instead of BufferedReader, then you can use nextInt() instead of parseInt().

import java.io.*;
import java.util.Scanner;

public class Main
{
	public static void main( String[] args ) throws IOException
	{
		Scanner in = new Scanner( System.in );
		int loop;
		int valueofy;
		int timesofnumber = 0;
		
		System.out.print( "Number of Loop: " );
		loop = in.nextInt();
		
		int[] input = new int[loop];
		for( int count = 0 ; count < loop ; count++ )
		{
			System.out.print( "INDEX [" + count + "]: " );
			input[count] = in.nextInt();
		}
	}
}

	}
}

it should be just bufferedreader

yes, if i put like this
Number of Loop: 5
INDEX [0]: 1
INDEX [1]: 2
INDEX [2]: 3
INDEX [3]: 3
INDEX [4]: 3

this index from 0-4 should display or declare them outside the loop how can i do that? so i can use them if i put if or compare them to the new input

Challenge: write code to accumulate ints into an array without using a loop. There is a straightforward and elegant way to do it. You can count elements in the array as you go, but that is awkward and it might not be necessary: you can use the length field of the array instead.

its already done,i did my calculation earlier and i made it,  i may closed this thread aha..

You can't keep me quiet that easily

int[] numbers =
      myScanner.tokens()
               .takeWhile(s -> new Scanner(s).hasNextInt())
               .mapToInt(Integer::praseInt)
               .toArray();

As an alternative, you can test a regex in line 3.

[edit] Somebody has pointed out a spelling mistake in my code. I am leaving finding it as an “exercise for the reader”.
