This is a question regarding casting of types in Java.
public int hashFunction(String D){
char[] Thing = D.toCharArray();
for(int i=0; i < Thing.length; i++){
index =+(int)Thing.length;
}
return index % tablesize;
}
Now how does the code work such that each content of the char array is now cast to a type int ?
Java will allow you to assign char
s to int
s, since int
has a larger domain than char
. This is known as widening :
char c = 'a';
int i = c; // compiles just fine
You probably want to access each element in Thing
, right? Use an enhanced for loop:
for(char c : Thing) {
// do something with c
}
