if it is a single letter of type char, you can directly subtract the zero of type char from the variable of type char and assign it to type int.

the code example is as follows: public? class? Test? {

public? static? void? main(String[]? args)? {

char? c? =? '4';

int? t? =? c? -? ''; < p p> System.out.println("char ("char converted to numbers:?" ? +? t);

}

}
