How should I properly initialize `char` variables?
My code:
```auto
String randomPlanetName(){
String name = "";
int dimension = int(random(3,12));
int repetitions = 0;
boolean lastType;
for(int i = 0;i == dimension;i++){
boolean type = boolean(int(random(0,1)));
char selection;
if(repetitions < 2){
type = !type;
}
if(type == true){
if(i == 0){
selection = upperCaseVowels[int(random(0,upperCaseVowels.length - 1))];
}else{
selection = lowerCaseVowels[int(random(0,lowerCaseVowels.length - 1))];
}
}
if(type == false){
if(i == 0){
selection = upperCaseConsonants[int(random(0,upperCaseConsonants.length - 1))];
}else{
selection = lowerCaseConsonants[int(random(0,lowerCaseConsonants.length - 1))];
}
}
name += selection;
lastType = type;
if(lastType == type){
repetitions++;
}else{
repetitions = 0;
}
}
return name;
}
```
Error: `The local variable "selection" may not have been initialized`
Thanks for reading, and thanks for answering!

`if(type == true){` -\> `if (type) {`
`if(type == false){` -\> `else {`

I’m suspicious that variable _type_ won’t ever be assigned `true` outta that expression. 🤔
You can do something like this instead: đź’ˇ
`final boolean type = random(2) < 1;`

Yeah, I also noticed that this function never work…

boolean type = round(random(0,2)) == 1;

No, it’s random true or false
(Oops, looks like I put the wrong code into it)

It don’t work even after changing the code…
Logic Error.

or
```auto
type=false;
if(random(1)<0.5)
type=true;
```

No, I don’t mean the random boolean, I mean the code.
```auto
void setup(){
}
void draw(){
println(randomPlanetName());
}
char[] upperCaseVowels = {
'A',
'E',
'I',
'O',
'U',
};
char[] lowerCaseVowels = {
'a',
'e',
'i',
'o',
'u',
};
char[] upperCaseConsonants = {
'B',
'C',
'D',
'F',
'G',
'H',
'J',
'K',
'L',
'M',
'N',
'P',
'Q',
'R',
'S',
'T',
'V',
'W',
'X',
'Y',
'Z',
};
char[] lowerCaseConsonants = {
'b',
'c',
'd',
'f',
'g',
'h',
'j',
'k',
'l',
'm',
'n',
'p',
'q',
'r',
's',
't',
'v',
'w',
'x',
'y',

};
char[] numbers = {
'0',
'1',
'2',
'3',
'4',
'5',
'6',
'7',
'8',
'9',
};
char seperator = ' ';
String randomPlanetName(){
String name = "";
int dimension = int(random(3,12));
int repetitions = 0;
boolean lastType;
for(int i = 0;i == dimension;i++){
boolean type = round(random(0,2)) == 1;
char selection;
if(repetitions > 2){
type = !type;
}
if(type){
if(i == 0){
selection = upperCaseVowels[int(random(0,upperCaseVowels.length))];
}else{
selection = lowerCaseVowels[int(random(0,lowerCaseVowels.length))];
}
}else{
if(i == 0){
selection = upperCaseConsonants[int(random(0,upperCaseConsonants.length))];
}else{
selection = lowerCaseConsonants[int(random(0,lowerCaseConsonants.length))];
}
}
name += selection;
lastType = type;
if(lastType == type){
repetitions++;
}else{
repetitions = 0;
}
}
return name;
}
```
The name returned will always be `""`.

An alternative (and very interesting) way to shift upper to lower case (and vice-versa) ASCII letters: 🤓
```auto
char letter = 'E';
println(letter); // E
char lower = (char) (letter | ' '); // e
println(lower);
char upper = (char) (lower & ~' '); // E
println(upper);
exit();
```

Alright.
```auto

if(type){
if(i == 0){
selection = upperCaseVowels[int(random(0,upperCaseVowels.length))];
}else{

}
}else{
if(i == 0){
selection = upperCaseConsonants[int(random(0,upperCaseConsonants.length))];
}else{
selection = lowerCaseConsonants[int(random(0,lowerCaseConsonants.length))];
}
}
name += selection;
lastType = type;//////////////////////////////////////////////////////////////// for easiness we use type to say vowel or consonant

so you mean : avoid the repetition of a vowel OR a consonant
so earth, Saturn and moon not allowed
