Allocates number within of array.

[Gustavo Siqueira]

Hello the all!
I want allocates number within of one array, see the program:

import java.util.Scanner;
public class Core {
	
	int[] class1; //declares an array of integers
	int[] class2; //declares other array of integers
	
	
	int select; //get data of user
	
	
	//creates Scanner for get dados of user
	Scanner input = new Scanner(System.in);
	
	public Core()
	{	
		class1 = new int[5]; //declares array for 5 class 
		class2 = new int[5]; //declares array for 5 class
		

		
		System.out.println("Please type 1 for First Classe :");
		select = input.nextInt();
		
		if(select == 1)
		{
			
			class1[0] = 1;
				
		}
		
		
		System.out.println("Class1: ");
		
		int i = 0;
		while(i <= class1.length)
		{
			System.out.println(class1[0]);
			i++;
		}
		
	
		
	}

}

See the result:

Class1:
1
1
1
1
1
1

Or is, this allocating in all memory of array.

How to solved the problem ?

You're printing the first element (class1[0]) each time.

Also, your loop condition should be while(i < class1.length); so < and not <=. Arrays in Java start at 0 and go to the length - 1 inclusive, or the length exclusive.
