it may seem simple but it posses lots of bugs I tried this way:
String s = gameList[0].toString();
s.replaceFirst(String.valueOf(s.charAt(0)),String.valueOf(Character.toUpperCase(s.charAt(0))) );
and it throws an exception
another try i had was :
String s = gameList[0].toString();
char c = Character.toUpperCase(gameList[0].charAt(0));
gameList[0] = s.subSequence(1, s.length());
rhis one also throws an Exception

If you are using an Android phone and Gboard, you can capitalize the first letter of any word with three touches. First, double-tap the word in question to highlight the word, then tap the shift button (the up arrow) on the keyboard to capitalize the first letter. Done!
The java. lang. Character. toUpperCase(char ch) converts the character argument to uppercase using case mapping information from the UnicodeData file.
The simplest way to capitalize the first letter of a string in Java is by using the String. substring() method: String str = "hello world!"; // capitalize first letter String output = str. substring(0, 1).
We can convert a char to a string object in java by using the Character. toString() method.
/**
* returns the string, the first char lowercase
*
* @param target
* @return
*/
public final static String asLowerCaseFirstChar(final String target) {
if ((target == null) || (target.length() == 0)) {
return target; // You could omit this check and simply live with an
// exception if you like
}
return Character.toLowerCase(target.charAt(0))
+ (target.length() > 1 ? target.substring(1) : "");
}
/**
* returns the string, the first char uppercase
*
* @param target

public final static String asUpperCaseFirstChar(final String target) {
if ((target == null) || (target.length() == 0)) {
return target; // You could omit this check and simply live with an
// exception if you like
}
return Character.toUpperCase(target.charAt(0))
+ (target.length() > 1 ? target.substring(1) : "");
