Converting a char to uppercase

Question

String lower = Name.toLowerCase();
int a = Name.indexOf(\" \",0);
String first = lower.substring(0, a);
String last = lower.substring(a+1);
char f = first.charAt(0);         


        

Answer 1

The easiest solution for your case - change the first line, let it do just the opposite thing:

String lower = Name.toUpperCase ();

Of course, it's worth to change its name too.

Answer 2

If you are including the apache commons lang jar in your project than the easiest solution would be to do:

WordUtils.capitalize(Name)

takes care of all the dirty work for you. See the javadoc here

Alternatively, you also have a capitalizeFully(String) method which also lower cases the rest of the characters.

Answer 3

You can apply the .toUpperCase() directly on String variables or as an attribute to text fields. Ex: -

String str;
TextView txt;

str.toUpperCase();// will change it to all upper case OR
txt.append(str.toUpperCase());
txt.setText(str.toUpperCase());

Answer 4

f = Character.toUpperCase(f);
l = Character.toUpperCase(l);
