I hope this helps you . I have two Strings, str1 and str2. How do I check if str2 is contained within str1, ignoring case? code :
str1.toLowerCase().contains(str2.toLowerCase())

Are there any way to apply regexp in java ignoring letter case?

this will help Simple example: we have string "Some sample string Of Text". And I want to filter out all stop words (i.e. "some" and "of") but I don't want to change letter case of other words which should be retained. , You can use the inline case-insensitive modifier: code :
str.replaceAll ("(?i)a|the|of|some|any", "");

Counting occurences of substring ignoring case in JAVA

This might help you You are picking up substrings that were mixed-case before - say, Div. This is not a good reason to count "div"s, though, because you would pick up parts of longer words (say, Division or Divorce). If you want a better count, you could use a simple regex to do the counting: code :
"[</]div[ />]"
Pattern countRx = Pattern.compile("[</]div[ />]", Pattern.CASE_INSENSITIVE);
Matcher m = countRx.matcher(sHtml);
int count = 0;
while (m.find()) {
count++;
}
System.out.println(count);

Ignoring upper case and lower case in Java

hope this fix your issue You have to use the String method .toLowerCase() or .toUpperCase() on both the input and the string you are trying to match it with. Example: code :
public static void findPatient() {
System.out.print("Enter part of the patient name: ");
String name = sc.nextLine();
System.out.print(myPatientList.showPatients(name));
}
//the other class
ArrayList<String> patientList;
public void showPatients(String name) {
boolean match = false;
for(matchingname : patientList) {
if (matchingname.toLowerCase.contains(name.toLowerCase())) {
match = true;
}
}
}

this will help , String.replace() doesn't support regex. You need String.replaceAll(). code :
DeleteLine.replaceAll("(?i)" + Pattern.quote(Checkout), "");
