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;}
A: if (count >;= 100) count = 0;
B: if (count >;= 100) {count = 0;}
C: if (count >;= 100)count = 0;
D: if (count >;= 100){count = 0;}
举一反三
- 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; } }
- 代码中myCount.count的值为（A）?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("myCount.count = " + myCount.count); } public static void increment(Count c, int times) { c.count++; times++; }} class Count { int count; Count(int c) { count = c; } Count() { count = 1; }} A: 101 B: 100 C: 99 D: 98
- 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")
- 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")
