在数组中追加多个值

var arr = [4, 5, 6];
arr.push(1, 2, 3);
console.log(arr); // 输出 [4, 5, 6, 1, 2, 3]

arr = [4, 5, 6]
arr.extend([1, 2, 3])
print(arr) # 输出 [4, 5, 6, 1, 2, 3]

import java.util.ArrayList;
import java.util.Arrays;

ArrayList<Integer> arr = new ArrayList<>(Arrays.asList(4, 5, 6));
arr.addAll(Arrays.asList(1, 2, 3));
System.out.println(arr); // 输出 [4, 5, 6, 1, 2, 3]

$arr = [4, 5, 6];
array_push($arr, 1, 2, 3);
print_r($arr); // 输出 Array ( [0] => 4 [1] => 5 [2] => 6 [3] => 1 [4] => 2 [5] => 3 )
