How can Java determine if two characters are equal?

In Java, you can use the == operator to determine if two characters are equal.

The example code is shown below:

char c1 = 'a';
char c2 = 'b';

if (c1 == c2) {
    System.out.println("两个字符相等");
} else {
    System.out.println("两个字符不相等");
}

In the above code, the == operator is used to compare variables c1 and c2 to see if they are equal. If they are equal, then output “The two characters are equal”; if not, output “The two characters are not equal”.
