Remove spaces from a String array

Question

How to remove spaces (not all spaces, just the beginning and end) from all indexes of a Java String array?

Answer 1

Using trim():

String[]  strArray = {" teste ", " teste ", " teste "};

for(int i = 0; i < strArray.length; i++){
  strArray[i]  = strArray[i].trim();
}

Answer 2

in the java-8 you can just do it this way:

String[] resultado = Arrays.stream(meuArray).map(String::trim).toArray(String[]::new);

Or you can make this version more "dirty" without creating a final array, the array passed will be modified automatically

Arrays.stream(meuArray).map(String::trim).toArray(unused -> meuArray);
