如何在JAVA中建立距离 [英] How to make a distance in JAVA

问题描述

我有一个问题。我有二维数组，4x4作为乘法表，我必须在列之间创建一个空格，使得m和m之间的间隙等于给定列+1中最后一个数字的长度。 
 
< pre> 
 1234 
 2468 
 36912 
 481216 

必看看

 1 2 3 4 
 2 4 6 8 
 3 6 9 12 
 4 8 12 16 
 

重点是每列之间的间距必须等于：+1列中最大数字的长度



我尝试了什么：

我尝试用循环做它没用完

解决方案

循环通过它，找到最大值。

然后你就可以工作了你需要多少空格（提示：任何值的日志 ₁₀ 的整数部分是数字减去1），并使用它来格式化所有数字正确。

I have a question. I have two-dimensional arrays with 4x4 as a multiplication table and I have to make a space between columns such that the gap between m and m is equal to the length of the last number in the given column +1.

<pre>
1234
2468
36912
481216

It must look

1 2  3  4
2 4  6  8
3 6  9 12
4 8 12 16

The point is that the spacing between each column must be equal to: the length of the largest number in the +1 column

What I have tried:

I tried to do it with a loop and it did not work out

解决方案

Loop though it, and find the largest value.
You can then work out how many spaces you need (hint: the integer part of the log₁₀ of any value is the number of digits minus 1), and use that to format all the numbers correctly.
