A. int count, count =0; B. int count = 0; C. count = 0; D. int count1 = 0, count2=l ;
int count1 = 0, count2=l ;
举一反三
- 下列语句中，哪个正确完成整形变量的声明和赋值 A: int conut,count=0; B: int count=0; C: count=0; D: int count1=0,count2=1;
- 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[]) { 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
- 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++])
- 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; } }
- 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

下列哪条语句是正确的?_______________ A: int count = 5; int* x = &count; B: int count = 5; int x = &count; C: int count = 5; int& x = &count; D: int count = 5; int** x = &count;

下面的代码段执行之后count的值是什么？ int count = 0; for....out.println(count);
- 2
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;}

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

以下哪个方法是正确的？ A: public static int Sum(int n, params int[] val){ int count = 0; foreach (int a in val){ count = count + a; } return count + n;} B: public static int Sum(params int[] val, int n){ int count = 0; foreach (int a in val){ count = count + a; } return count + n;} C: public static int Sum(params int[] v1, params int[] v2){ int c1 = 0, c2 = 0; foreach (int a in v1){ c1 = c1 + a; } foreach (int a in v2){ c2 = c2 + a; } return c1 + c2;} D: public static int Sum(params int[] v, char ch){ int c = 0; foreach (int a in v){ c = c + a; } return c + ch;}
