有如下类定义: class Test { int x_,y_; public: Test ():a_(0) ,b_(0) {} Test(int a,int b=0) :a_(a),b_(b){} }; 若执行语句 Test x(2) ,y[3],*z[4]; 则Test类的构造函数被调用的次数是( )。

下列程序的输出结果是 ( ) class Derao { void test() { Systeme.out.print("NO")；} void test (int i) {System.out.print(a);} void test(int a，int b) {System.out.print(a+b)；} } class Test { public static void main(String args[]) { Demo de=new Demo()； de.test()； de.test5.； de.test(6，8)； } }

下列程序的输出结果是 class Demo { void test( ) { Systeme.out.pnnt("NO")；} void test(int i) { System.out.print(a)；} void test(int a，int b) { System.out.print(a+b)；} } class Test { public static void main(String args[ ] ) { Demo de=new Demo( )； de.test( )； de.test(5)； de.test(6，8)； } }
