多个字符串数组合并成一个新的字符串数组

publicclassCeshi{
 publicstaticvoidmain(String[]args)throwsParseException{

  String[]str1={"J","a","v","a","中"};
  String[]str2={"如","何","把","两","个","数","组","合","并","为",
    "一","个"};

  intstrLen1=str1.length;//保存第一个数组长度
  intstrLen2=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

 }
