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
A: 0
B: 1
C: 2
D: 3
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; } }
- 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
- 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
- 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
- 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
