這樣寫呢？
public?class?HelloWorld{ ?public?static?void?main(String[]?args)?{ ?final?char?SEX_1?=?'男'; ?final?char?SEX_2=?'女'; ????System.out.println(SEX_1); ????System.out.println(SEX_2); ?} ?}2016-04-17
public?class?HelloWorld{ ????public?static?void?main(String[]?args)?{ ????????final?String?SEX_1="男"; ????????final?String?SEX_2="女"; ????????System.out.println(SEX_1+SEX_2); ????} }上面格式有點錯，這樣也通過不了
