阅读以下程序public class Count{static int count;int number;public Count(){count = count + 1;number = count;}}class Test{public static void Main(){Count a = new Count();Count b = new Count();Count c = new Count();}}程序运行后,对象a的count值是() A: 0 B: 1 C: 2 D: 3

下列if语句中,程序风格最规范的是()。 A: if (count >;= 100) count = 0; B: if (count >;= 100) {count = 0;} C: if (count >;= 100)count = 0; D: if (count >;= 100){count = 0;}

给定一个Java程序的代码如下所示,则编译运行后,输出结果是 ( )。 public class Test { int count = 9; public void count() { System.out.println("count=" + count++); } A: blic static void main(String args[]) new Test().count(); new Test().count();}} B: count=9 count=9 C: count=10 count=9 D: count=10 count=10 E: count=9 count=10
