有如下程序 public class Test { int a,b; Test() { a=100; b=200; } Test(int x,int y) { a = x; b = y; } public static void main(String args[]) { Test Obj1=new Test(12,45); System.out.println('a = 'Obj1.a+' b= '+Obj1.B) ; Test Obj1=new Test(); System.out.println('a = 'Obj1.a+' b= '+Obj1.B) ; } } 程序的运行结果为( )。
