举一反三
- 以下代码能否编译通过，假如能编译通过，运行时得到什么输出结果（）。 <% request.setAttribute("count",newInteger(0)); Integer count = request.getAttribute("count") ; %> <%=count%>
- 以下代码能否编译通过，假如能编译通过，运行时得到什么输出结果（）。 <% req...t") ; %> <%=count %>
- 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
- 48. 以下Java代码片段编译运行的结果是。 int [] a = {1,2,3,4,5}; for (int count = 0 ; count<5; count ++) System.out.print(a[count++]) int [] a = {1,2,3,4,5}; for (int count = 0 ; count<5; count ++) System.out.print(a[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

下列程序运行后，输出结果为_________ count=0 for letter in 'Python': count=count+1 if letter == 'h': break print(count)
- 1
下面的代码段的输出结果为？ int count = 0; for (int i ....out.println(count);
- 2
执行下述代码: count = 5 def print_num(): count = 2 count += 1 print(count) 当调用print_num()函数时,输出结果为( )
- 3
执行以下程序段后,数组b中的元素个数有________个。Dim a() As Integer = {2, 15, 9, 4, 5, 56, 74, 8, 43, 10}Dim b(9) As IntegerDim count As Integer = 0Dim i As IntegerFor i = 0 To UBound(a)If a(i) Mod 2 = 0 Thenb(count) = a(i)count += 1End IfNextReDim Preserve b(count - 1)

写出下列程序的输出结果 public class Test { public static void main(String[] args) { Count myCount = new Count(); int times = 0; for(int i=0;i<100;i++) increment(myCount , times); System.out.println(“count is” + myCount.count); System.out.println(“time is”+ times); } public static void increment(Count c , int times) { c.count++; times++; } } class Count { public int count; Count(int c) { count =c; } Count() { count =1; } }
