为什么输不出男和女

Question

public class HelloWorld{

    final char SEX1='男';

    final char SEX2='女';

    public static void main(String[] args) {

        System.out.println("SEX1");

        System.out.println("SEX2");

        

Answer 1

用双引号包起来就是字符串而不是变量了，但直接System.out.println(SEX1)会找不到变量，因为SEX1是非静态变量。所以要么把SEX1变成静态的，final static char SEX1='男'。要么new了对象再访问，HelloWorld helloWorld=new HelloWorld(); System.out.println(helloWorld.SEX1)
