Method

booleanstartsWithIgnoreCase(String s, String prefix)
Returns true iff s starts with prefix, ignoring case. 
final int pl = prefix.length();
if (s.length() < pl)
    return false;
for (int i = 0; i < pl; i++) {
    char sc = s.charAt(i);
    char pc = prefix.charAt(i);
    if (sc != pc) {
        sc = Character.toUpperCase(sc);
...
booleanstartsWithIgnoreCase(String s, String start)
Check is a string starts with another string, ignoring the case. 
if (s.length() < start.length()) {
    return false;
return s.substring(0, start.length()).equalsIgnoreCase(start);
booleanstartsWithIgnoreCase(String s, String w)
starts With Ignore Case 
if (w == null)
    return true;
if (s == null || s.length() < w.length())
    return false;
for (int i = 0; i < w.length(); i++) {
    char c1 = s.charAt(i);
    char c2 = w.charAt(i);
    if (c1 != c2) {
...
booleanstartsWithIgnoreCase(String searchIn, int startAt, String searchFor)
starts With Ignore Case 
return searchIn.regionMatches(true, startAt, searchFor, 0, searchFor.length());
booleanstartsWithIgnoreCase(String searchIn, int startAt, String searchFor)
Determines whether or not the string 'searchIn' contains the string 'searchFor', dis-regarding case starting at 'startAt' Shorthand for a String.regionMatch(...) 
return searchIn.regionMatches(true, startAt, searchFor, 0, searchFor.length());
booleanstartsWithIgnoreCase(String searchIn, String searchFor)
 Determines whether or not the string 'searchIn' contains the string 'searchFor', dis-regarding case. 

return startsWithIgnoreCase(searchIn, 0, searchFor);
booleanstartsWithIgnoreCase(String seq, String prefix)
Tests if the string sequence starts with the specified prefix, case insensitive. 
return seq.toLowerCase().startsWith(prefix.toLowerCase());
booleanstartsWithIgnoreCase(String startString, String anotherString)
check whether a string starts with anotherString (ignore case) 
int length = startString.length();
if (length > anotherString.length()) {
    return false;
if (startString.equalsIgnoreCase(anotherString.substring(0, length))) {
    return true;
} else {
    return false;
...
booleanstartsWithIgnoreCase(String str, String prefix)
starts With Ignore Case 
if (str == null || prefix == null) {
    return false;
final int len = prefix.length();
if (str.length() < len) {
    return false;
return str.regionMatches(true, 0, prefix, 0, len);
...
booleanstartsWithIgnoreCase(String str, String prefix)

Case insensitive check if a String starts with a specified prefix.

return startsWith(str, prefix, true);
