I'm new to java and currently I'm learning strings.
How to remove multiple words from a string? I would be glad for any hint.
The replacement doesn't work as it deletes a part of a word.
class WordDeleterTest {
public static void main(String[] args) {
WordDeleter wordDeleter = new WordDeleter();
// Hello
System.out.println(wordDeleter.remove("Hello Java", new String[] { "Java" }));
// The Athens in
System.out.println(wordDeleter.remove("The Athens is in Greece", new String[] { "is", "Greece" }));
// This cat
System.out.println(wordDeleter.remove("This is cat", new String[] { "is" }));
}
}
class WordDeleter {
public String remove(String phrase, String[] words) {
String result = phrase;
for (String word : words) {
result = result.replace(word, "");
}
return result.trim();
}
}
Output:
Hello
The Athens in
Th cat
class WordDeleter {
public String remove(String phrase, String[] words) {
String result = phrase;
for (String word : words) {
result = result.replaceAll("\\b" + word + "\\b", "");
}
return result.trim().replaceAll(" +", " ");
}
}
