How do you compare char values?

The compare(char x, char y) method of Character class is used to compare two char values numerically. The final value returned is similar to what would be returned by: Character. valueoOf(x)….Return Value

1. a value 0 if x==y.
2. a value less than 0 if x
3. a value greater than 0 if x>y.

Finally, the string contains the string form of the characters.

Is there a way to compare primitive chars in Java?

It is simplest approach and does not involve any class or method. You can compare primitive chars either using Character.compare () method or equals () method. You can use compare () method with Character objects as well. The compare () method of Characters class returns a numeric value positive, negative or zero.

Where do you find the number of a Unicode character?

Each Unicode character has its own number and HTML-code. Example: Cyrillic capital letter Э has number U+042D (042D – it is hexadecimal number), code ъ.
