多个数组内容拼接,每个数组分别根据索引位置,拼接内容

1,通过Hutool.ArrayUtil.zip方法进行处理(缺点,只能保留最短的数组内容)

public class Test {
    public static void main(String[] args) {
        String chinese = "张三;李四;王五";
        String english = "zhangsan;lisi";
        String age = "11;";

        String[] a1 = chinese.split(";");
        String[] a2 = english.split(";");
        String[] a3 = age.split(";");
        
        Map<String, String> zip = ArrayUtil.zip(a1, a2);
        System.out.println("zip = " + zip);
    }

}

结果

zip = {李四=lisi, 张三=zhangsan}

2,程序逻辑实现(短数组通过填充,解决数组越界)


public class Test {
    public static void main(String[] args) {
        String chinese = "张三;李四;王五";
        String english = "zhangsan;lisi";
        String age = "11;";

        String[] a1 = chinese.split(";");
        String[] a2 = english.split(";");
        String[] a3 = age.split(";");

        int[] lengthArr = {a1.length, a2.length, a3.length};
        int max = ArrayUtil.max(lengthArr);

        String[] t1 = transfer(max, a1);
        String[] t2 = transfer(max, a2);
        String[] t3 = transfer(max, a3);

        String[] todo = new String[max];

        for (int i = 0; i < max; i++) {
            todo[i] = t1[i] + " " + t2[i] + " " + t3[i];
        }
        System.out.println(Arrays.asList(todo));
    }

    private static String[] transfer(int max, String[] a1) {
        String[] m1 = new String[max];
        for (int i = 0; i < m1.length; i++) {
            if (a1.length - 1 >= i) {
                m1[i] = a1[i];
            } else {
                m1[i] = "";
            }
        }
        return m1;
    }
}

结果

[张三 zhangsan 11, 李四 lisi , 王五  ]
