public class HelloWorld{
??? public static void main(String[] args) {
??? final char="男";???
??? final char="女";
??? System.out.println(a);
??? System.out.println(b);
??? }
}

觀察到結(jié)果如下

HelloWorld.java:3:?error:?incompatible?types:?String?cannot?be?converted?to?char
	final?char?a="男";	
	?????????????^
HelloWorld.java:4:?error:?incompatible?types:?String?cannot?be?converted?to?char
	final?char?b="女";
	?????????????^
2?errors
