转换1-D字符串数组到2-D字符数组 [英] Converting 1-D String array to 2-D char array
本文介绍了转换1-D字符串数组到2-D字符数组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的工作,需要我采取从文件一维字符串数组,并把它变成一个二维数组的程序。以数组中从文件工作正常,但我不能得到第二部分的工作。
I'm working on a program that requires me to take in a 1-D String array from a file and turn it into a 2-D array. Taking in the array from the file works fine, but I can't get the second part to work.
在code我工作是:
char[][] array2 = new char [7][5];
for (int i = 0; i < array1.length; i++)
{
array2[i]= array[i].toCharArray();
}
for (int i = 0; i < 5; i++)
{
for (int j = 0; j < 7; j++)
{
System.out.println(array2[i][j]);
}
}
阵列应该在网格格式打印,但是被向下打印。
The array is supposed to print in a grid format, but is printing downward.
任何帮助是AP preciated,谢谢。
Any help is appreciated, thanks.
推荐答案
使用打印
而不是的println
在内环和每次循环后打印为空白行的println
。
Use print
instead of println
in inner loop and after each loop print a blank line with println
.
for (int i = 0; i < 7; i++) // see changes 5/7. You did "new char[7][5]" not [5][7]
{
for (int j = 0; j < 5; j++) // see changes 7/5
{
System.out.print(array2[i][j]);
}
System.out.println();
}
更新:
下面是一个转换String数组二维字符数组的程序。
Following is a program that convert String array to 2D char array.
public class StringToChar {
public static void main(String[] args) {
String[] strArr = { "HELLO", "WORLD" };
char[][] char2D = new char[strArr.length][];
for (int i = 0; i < strArr.length; i++) {
char2D[i] = strArr[i].toCharArray();
}
for (char[] char1D : char2D) {
for (char c : char1D)
System.out.print(c + " ");
System.out.println();
}
}
}
