B.
If the angular speed is constant, the object is not accelerated.
C.
The object has a tangential acceleration only if the disk has an angular acceleration.
D.
If the disk has an angular acceleration, the object has both a centripetal acceleration and a tangential acceleration.

【多选题】分析以下代码: public class Test1 { public Object max(Object o1, Object o2) { if ((Comparable)o1.compareTo(o2) >= 0) { return o1; } else { return o2; } } }
A.
该程序有一个编译错误,因为Test1没有主要方法。
B.
该程序有一个编译错误,因为o1是一个Object实例,并且它没有compareTo方法。
C.
该程序出现编译错误,因为您无法将Object实例o1强制转换为Comparable。

【单选题】Analyze the following code: public class Test1 { public Object max(Object o1, Object o2) { if ((Comparable)o1.compareTo(o2) >= 0) { return o1; } else { return o2; } } }
A.
The program has a syntax error because Test1 does not have a main method.
B.
The program has a syntax error because o1 is an Object instance and it does not have the compareTo method.
C.
The program has a syntax error because you cannot cast an Object instance o1 into Comparable.
D.
The program would compile if ((Comparable)o1.compareTo(o2) >= 0) is replaced by (((Comparable)o1).compareTo(o2) >= 0).
