[Q#7478210][A#7478238] How to search a char array for a specific char?

https://stackoverflow.com/q/7478210

Lets say I have a char array that contains the sequences of chars: "robots laser car" I want to search for spaces in this char array in order to identify each separate word. I wanted to do something like this pseudocode below: for lengthOfArray if array[i].equals(" ") doSomething(); But I cant find array methods to that comparison.

It's not exactly what you're asking for, but I'll throw it out there anyway: if you have a String instead of a char array, you can split by whitespace to get an array of strings containing the separate words. The \s+ regular expression matches one or more whitespace characters (space, carriage return, etc.), so the string will be split on any whitespace.

APIzation

String s = new String(array);
String[] words = s.split("\\s+");
// words = { "robots", "laser", "car" }

package com.stackoverflow.api;

public class Human7478238 {

  public static String[] splitStringBySpaces(String array) {
    String s = new String(array);
    String[] words = s.split("\\s+");
    return words;
  }
}
