如何把两个数组内容混合拼接成一个数组内容

如何把两个数组内容混合拼接成一个数组内容

另外声明一个足够长的，先把第一个数组付给他，再把第二个数组接在后面

import java.util.arrays; //java中如何把两个数组合并为一个 public class gog { public static void main(string[] args) { string [] str1 = {"j","a","v","a","中"}; string [] str2 = {"如","何","把","两","个","数","组","合","并","为","一","个"}; int strlen1=str1.length;//保存第一个数组长度 int strlen2=str2.length;//保存第二个数组长度 str1= arrays.copyof(str1,strlen1+ strlen2);//扩容 system.arraycopy(str2, 0, str1, strlen1,strlen2 );//将第二个数组与第一个数组合并 system.out.println(arrays.tostring(str1));//输出数组 } }
