hello again... i've been stuck in this problem earlier....

how can you delete an element in an array and then print the array minus the deleted item???
thank you!!!








*i'm really just a noob here.... all i can do now are simple programs....*sigh*

You could:
1 - Use a List
2 - Use a second array of booleans, the same size as the other array, that tells you for every element if it's "deleted" or not.
For example:

int [] array = new int[10];
boolean [] controlArray = new boolean[10];

...

private void deleteElement(int elementPosition){
    controlArray[elementPosition]=false;
}

...

private void printArray(){
   for(int i=0;i<10;i++){
      if(controlArray[i])
         System.out.print(array[i]+" ");
   }

}

private int[] array = new int[10];
...
...
private void removeElement(int index){
  int[] tempArray = new int[array.length];
  int counter;
  for(int i=0 ; i<array.length ; i++){
    if(index != i){
      tempArray[counter++] = array[i];
    }
  }

  array = tempArray;
}

public void print(){
  for(int i=0 ; i<array.lenghth ; i++){
    System.out.print(array[i] + " ");
  }
}

That's another way to go!
Or you could use System.arrayCopy to implement the code oxano posted. It should be faster.
