如何从数组中的所有元素修剪空白？ [英] How to trim white space from all elements in array?

问题描述

我只是想知道从列表的所有元素中移除空格的最佳方法是什么。

例如，如果我有 String [] array = {String，Tom Selleck，Fish}
我怎么能得到所有元素 {String ，Tom Selleck，Fish}

谢谢！

试试这个：

  String [] trimmedArray = new String [array.length]; 
 for（int i = 0; i< array.length; i ++）
 trimmedArray [i] = array [i] .trim（）; 
  

现在 trimmedArray 包含与 array ，但没有前导和尾随空格。或者，你可以写这个来在同一个数组中就地修改字符串：

  for（int i = 0; i < array.length; i ++）
 array [i] = array [i] .trim（）; 
  

I was just wondering what the best way to remove the white space from all the elements of a list would be.

For example if I had String [] array = {" String", "Tom Selleck "," Fish "} How could I get all the elements as {"String","Tom Selleck","Fish"}

Thanks!

解决方案

Try this:

String[] trimmedArray = new String[array.length];
for (int i = 0; i < array.length; i++)
    trimmedArray[i] = array[i].trim();

Now trimmedArray contains the same strings as array, but without leading and trailing whitespace. Alternatively, you could write this for modifying the strings in-place in the same array:

for (int i = 0; i < array.length; i++)
    array[i] = array[i].trim();
