菜鸟求助，lambda表达式使用问题
static {
Thread t1 = new Thread(new Runnable() {
@Override
public void run() {
System.out.println(abc); //works
}
});
Thread t2 = new Thread(() -> {
System.out.println(abc); //illegal forward reference
});
t1.start();
t2.start();
}
private static String abc = "test"; //declare after static block
public static void main(String args[]) {
System.out.println("main：" + DataAnalyseTest.abc);
} 第一种声明方式为什么可以使用后面的静态变量但是第二种不可以。。。#Java#
