CountDownLatch的downCount（）方法功能是（）。 A: 使得count+1B．使得count-1C．count变为0 B: count不变 C: 使得count+1 D: 使得count-1 E: count变为0 F: count不变

使用while 语句实现打印出1至10.count = 1while ( ) print (count) count = count + 1 A: count B: True C: count D: count

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

count = 0 while count < 5: print (count, " 小于 5") count = count + 1 else: print (count, " 大于或等于 5")

下列程序的运行结果是（   ）。 count = 0 while count < 5: print(count, " is less than 5") count = count + 1 else: print(count, " is not less than 5")

class Count {public int count;public Count（int c） {count = c;}public Count（）{count = 1;}}public class Test {public static void increment（Count c, int times） {c.count++;times++;}public static void main A: myCount.count=4 times=0 B: myCount.count=4 times=1 C: myCount.count=3 times=1 D: myCount.count=3 times=0

下面的代码段执行之后count的值是什么( ) int count = 1; for (int i = 1; i <= 5; i++) { count += i; } System.out.println(count);

将变量$count增1，下面哪种方式是正确的？（ ） A: $count =+1; B: ++ count; C: count++; D: $count++;

以下程序段的输出结果是（ ）。[img=294x478]17e43bcb95a3936.png[/img] A: count= 1 B: count=2 C: count=3 D: count=4

class Count { public int count; public Count(int c) { count = c; } public Count() { count = 1; }}public class Test { public static void increment(Count c, int times) { c.count++; times++; } public static void main(String args&#91;&#93;) { Count myCount = new Count(); int times = 0; for (int i = 0; i A: myCount.count=4 times=0 B: myCount.count=3 times=0 C: myCount.count=4 times=1 D: myCount.count=3 times=1
