1. 转型打印

System.out.println(Arrays.toString(arr));
System.out.println(Arrays.asList(arr));
System.out.println(Arrays.deepToString(arr));

2. 流循环打印

Arrays.asList(arr).stream().forEach(s -> System.out.println(s));

3. 对象和数组循环打印

for(int n: arr){
    System.out.println(n+", ");
}

for (int i = 0; i < arr.length; i++) {

    System.out.print(arr[i] + ", ");
}
