System.out.println("sex"+MALE);System.out.println("sex"+FEMALE);

public class HelloWorld{

    public static void main(String[] args) {

final String MALE="男";

final String FEMALE="女";

    System.out.println("MALE："+MALE);

    System.out.println("FEMALE："+FEMALE);

}

}

逗比。sex没定义，；没加

package ex1;

public class Helloword {

public static void main(String[] args){

final String MALE="男";

final String FEMALE="女";

System.out.println(MALE);

System.out.println(FEMALE);}

}

你SEX没定义

 System.out.pintln("MALE"+SEX);            应为println

System.out.println("FEMALE"+SEX)           句尾要分号

}

.pintln  你这里单词拼错了

 System.out.println("MALE"+SEX);
