split String by space separated

I need to split words by space separated in java, so I have used .split function in-order to achieve that like as shown below

String keyword = "apple mango ";
String keywords [] = keyword .split(" ");

The above code is working fine but the only is that I sometimes my keyword will contain keyword like "jack fruit" , "ice cream" with double quotes like as shown below

String keyword = "apple mango \"jack fruit\" \"ice cream\"";

In this case I need to get 4 words like apple, mango, jack fruit, ice cream in keywords array

Can anyone please tell me some solution for this

List<String> parts = new ArrayList<>();
String keyword = "apple mango \"jack fruit\" \"ice cream\"";

// first use a matcher to grab the quoted terms
Pattern p = Pattern.compile("\"(.*?)\"");      
Matcher m = p.matcher(keyword);
while (m.find()) {
    parts.add(m.group(1));
}

// then remove all quoted terms (quotes included)
keyword = keyword.replaceAll("\".*?\"", "")
                 .trim();

// finally split the remaining keywords on whitespace
if (keyword.replaceAll("\\s", "").length() > 0) {
    Collections.addAll(parts, keyword.split("\\s+"));
}

for (String part : parts) {
    System.out.println(part);
}

Output:

jack fruit
ice cream
apple
mango
