Is this a basic Java I prodject? you should be able to look up arrays in your books index. There are a couple different ways to declare an array, one of which is;

int [] Intarr = new int[20];

int is the data type in this array, new int, creates the array, 20 is the number of positions. As for sequentially accessing it, do you know what a for loop is?

Something like this?

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
class ArrayOfInts
{
  public static void main(String[] args)
  {
     int[] myNums = new int[20];
 
    for (int x=0; x<20; x++)
    {
        myNums[x] = x * 5;
    }
 
    for (int y=0; y<myNums.length; y++)
	{
	  System.out.println("myNums[" + y + "] = " + myNums[y]);
	}
 
  }
}
class ArrayOfInts
{
  public static void main(String[] args)
  {
     int[] myNums = new int[20];

    for (int x=0; x<20; x++)
    {
        myNums[x] = x * 5;
    }
   
    for (int y=0; y<myNums.length; y++)
	{
	  System.out.println("myNums[" + y + "] = " + myNums[y]);
	}
	 
  }
}

tht's very easy

class Test{
public static void main(String args[]){
int[] arr = new int[20];
for(int j=0;j<20;j++){
arr[j]=j;
}
for(int i=0;i<arr.length;i++){

System.out.println(arr[i]);
}
}
}
arr is array containing 20 integers
this will print first 20 from 0 to 19
this will do the job

Of course it was easy for you. You basicly copied my code above.
