Converting the square root sign from string to char

Question

In order to get the char version of "\u221A" (aka the square root sign), would I just do the following:

String op = "\u221A";
char operator = op.charAt(0);

operator = '\u221A';

The last part doesn't seem right. Just wondering how I'd go about doing that. Thanks for your help!

Answer 1

Using the hex literal directly seems simpler than either of the approaches you state, although they all have the same effect.

public class Test {
  public static void main(String[] args) {
    String op = "\u221A";
    char operator1 = op.charAt(0);
    char operator2 = '\u221a';
    char operator3 = 0x221a;
    System.out.println(operator1 == operator2);
    System.out.println(operator2 == operator3);
  }
}
