for(int i = 0,k = 0; i < array.length; i++){
arr[k++] = array[i];

// Check if array filled for add new element

arr[arr.length+1] will give you error indexoutofbounds. ..

public static int[] addElement(int[] array, int elem){

int[] arr = new int[array.length +1];

for(int i = 0,k = 0; i < array.length; i++)
arr[k++] = array[i];

arr[k] = elem;

return arr;
}
