如何将一维数组转换为需要的二维数组

截取字符串后，一般都会得到一个一维数组，有时需要把这个以为数组转成相应行与列的二维数组。最大的不同便在于行数与列数的规定。下面是一个简单的例子，行与列可根据实际情况来取到，或规定。

public class ArrayTest {
 public static void main(String[] args) {
  String body [] ={
    "0.0.0.0"  ,  "0.0.0.0"   , "255.0.0.0"  ,  "U"   ,  "0"   ,   "0"   ,   "0" , "x" ,

  };
  String[][] arr = new String[6][8];//
  System.out.println(arr.length);
