how to convert from string("a") to char..

[Eung maeng]

Hi,
Does anyone explain to me how to convert from string("Y") to char?

THANKS

String y = "Y";
char y_char = y.charAt(0);

And if the string is bigger than 1 letter you can do the same thing with a loop or break up the string and send it into a character array with the following:

String y = "hello";
char[] array = y.toCharArray();

array = {'h', 'e', 'l', 'l', 'o'}

I plan to use the following method to convert String to char:

 
public class StringToChar {

public static final char NULL_CHAR = 0;

public static char strToChar(String str) {
if (str == null) {
return NULL_CHAR;
} else if (str.length() <= 0) {
return NULL_CHAR;
} else {
return str.charAt(0);
}
}
 
public static void main(String[] args) {
String str = "Y";
System.out.println(strToChar(str));
str = "";
System.out.println(strToChar(str));
str = null;
System.out.println(strToChar(str));
}

}

This code doesn't throw an exception, but it doesn't print the null characters either.

Is this OK?
