将数据添加到数组Java

int[] originalArray = {1, 2, 3, 4, 5};
int[] newArray = new int[originalArray.length + 1];

for (int i = 0; i < originalArray.length; i++) {
    newArray[i] = originalArray[i];
}

newArray[newArray.length - 1] = 6; // 添加新元素

System.out.println(Arrays.toString(newArray));

ArrayList<Integer> arrayList = new ArrayList<>();
arrayList.add(1);
arrayList.add(2);
arrayList.add(3);
arrayList.add(4);
arrayList.add(5);
arrayList.add(6); // 添加新元素

System.out.println(arrayList);

int[] originalArray = {1, 2, 3, 4, 5};
int[] newArray = Arrays.copyOf(originalArray, originalArray.length + 1);
newArray[newArray.length - 1] = 6; // 添加新元素

System.out.println(Arrays.toString(newArray));
