java如何访问类中的全局变量

Java code

public class helloJava {
String say="我要学会";
public static void main(String[] arge){
    String say="aaaaaa";
    System.out.println("你好,java"+say);
    System.out.println("你好,java"+say);
}
}

现在输出的是main方法中的say 我现在想输出"我要学会"这个say,该如何输出呢？

------解决方案--------------------
public class HelloJava {

private String say="我要学会";

public String getSay() {
return say;
}

public void setSay(String say) {
this.say = say;
}

public static void main(String[] arge){
String say="aaaaaa";
HelloJava hello=new HelloJava();
// System.out.println("你好,java"+say);
System.out.println("你好,java"+hello.getSay());
}


}
