java - How to trim white space from all elements in array?

Question

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!

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();
