题目内容 (请给出正确答案)

下列程序段的输出结果是______。 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 Obj2=new Test( ); System.out.println("a="+Obj1.a+"b="+Obj1.B); } }

A.a=100 b=200 a=12 b=45

B.a=12 b=45 a=100 b=200

C.a=12 b=200 a=100 b=45

D.a=100 b=45 a=12 b=200
