    Default Array (simple).

    This code should allow the user to input the array length (less that 10), input data into the array, then view the data in the array. What is wrong with the code, and how do I fix it?

    import java.util.Scanner;
     
    public class Array {
     
    	public static void main(String[] args) {
    		Scanner input = new Scanner(System.in);
     
    		int length;
    		int[] numbers;
    		int counter;
    		int count;
     
    		System.out.print("Length: ");
    		length = input.nextInt();
    		numbers = new int[length];
     
    		if(length <= 10){
    			for(counter = 0; counter < numbers.length; counter++);
    				{count = counter + 1;
    				System.out.println("Number "+count+": ");
    				numbers[counter] = input.nextInt();}
     
    			for(counter = 0; counter < numbers.length; counter++);
    				{System.out.println("Number "+counter+": "+numbers[counter]);}}
     
    		else{System.out.println("Too big");}
    	}
     
    }

    you should post the errors you get...
    anyway why do you put a semicolon ; after the for loop? doing that you stop the loop there and leave alone the code below
    delete that semicolon and everything will work, the code should be like that

    for(int i; i<5;i++){
    //code
    }
