如何避免在java中替换文本中的特定单词

String text = "I have an apple.";
String replacedText = text.replace("apple", "orange");
System.out.println(replacedText);

String text = "I have an apple and an application.";
String replacedText = text.replaceAll("\\bapple\\w*", "orange");
System.out.println(replacedText);

String text = "I have an apple.";
StringBuilder builder = new StringBuilder(text);
int index = builder.indexOf("apple");
while (index != -1) {
    builder.replace(index, index + "apple".length(), "orange");
    index = builder.indexOf("apple", index + "apple".length());
}
String replacedText = builder.toString();
System.out.println(replacedText);
