使用三目运算符的小细节

public static void main(String[] args) {
    Object o1 = true ? new Integer(1) : new Double(2.0);
    Object o2;
if (true) {
    o2 = new Integer(1);
} else {
    o2 = new Double(2.0);
}
    System.out.print(o1);
    System.out.print(" ");         
    System.out.print(o2);
}

 Object o1 = true ? new Integer(1) : new Double(2.0);
