classAccount{privateintbalance;publicvoidsetBalance(intb){balance=b;}publicintgetBalance(){returnbalance;}publicvoidclearBalance(){balance=0;}}哪一个改变可以使Account类线程安全?()

The town has its own public library and public gardens.（英译中)

对于类定义：class A{public：virtual void funcl（){}void func2（){})；class B：public A{public：vo

关于以下程序段的说法正确的是 1. public class Myar{ 2. public st

以下代码有问题 下列说法正确的是()。代码如下:public A{public void method(){} (1)public string method(){} (2)public string method(int a){} (3)}

以下程序的调试结果为?public class Outer{public String name = Outer;public stat

下面的程序能正确运行吗 public class NULL { public static void haha(); } }
