classCount{publicintcount;publicCount(intc){count=c;}publicCount(){count=1;}}publicclassTest{publicstaticvoidincrement(Countc,inttimes){c.count++;times++;}publicstaticvoidmain(Stringargs[]){CountmyCount=newCount();inttimes=0;for(inti=0;i<3;i++)increment(myCount,times);System.out.println("myCount.count="+myCount.count+"times="+times);}}程序的运行结果正确的是（）
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
- 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
- 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); int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count);
