交叉合并：如字符串一为：abcd  字符串二为：1234

则结果为：a1b2c3d4

1 import java.util.ArrayList; 2 import java.util.List; 3  4 public class A { 5     public static void main(String[] args) { 6         String a[] ={"a","b","c"}; 7         String b[] ={"1","2","3"}; 8         CombineTwoArray(a, b); 9         System.out.println(CombineTwoArray(a, b));10     }11 12     public static List
     
       CombineTwoArray(String[] first, String[] second) {13         List
      
        outlist = new ArrayList
       
        ();14         int index = 0;15         while (index < first.length && index < second.length) {16             outlist.add(first[index]);17             outlist.add(second[index]);18             ++index;19         }20         if (index >= first.length) {21             for (int i = index; i < second.length; i++) {22                 outlist.add(second[i]);23             }24         } else {25             for (int i = index; i < first.length; i++) {26                 outlist.add(first[i]);27             }28         }29         return outlist;30     }31 }
       
      
     

用js的写法:

1  2  3        4      5     13     61   62    63   64         
     
      65
