如何删除空的数组，如果值不为空，则只显示数组，并显示给用户

let arrays = [[], [1, 2, 3], [], ['a', 'b'], []];
let nonEmptyArrays = arrays.filter(array => array.length > 0);
console.log(nonEmptyArrays); // 输出: [ [1, 2, 3], ['a', 'b'] ]

arrays = [[], [1, 2, 3], [], ['a', 'b'], []]
non_empty_arrays = [array for array in arrays if array]
print(non_empty_arrays)  # 输出: [[1, 2, 3], ['a', 'b']]

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

public class Main {
    public static void main(String[] args) {
        List<List<Integer>> arrays = new ArrayList<>();
        arrays.add(new ArrayList<>());
        arrays.add(Arrays.asList(1, 2, 3));
        arrays.add(new ArrayList<>());
        arrays.add(Arrays.asList('a', 'b'));
        arrays.add(new ArrayList<>());

        List<List<Integer>> nonEmptyArrays = new ArrayList<>();
        for (List<Integer> array : arrays) {
            if (!array.isEmpty()) {
                nonEmptyArrays.add(array);
            }
        }
        System.out.println(nonEmptyArrays); // 输出: [[1, 2, 3], [a, b]]
    }
}
