下面程序段的输出结果为 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("="+Obj2.a+" b="+Obj2.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
