下面的方法,当输入为2的时候返回值是多少?( ) public static int getValue(int i) { int result = 0; switch (i) { case 1: result = result + i; case 2: result = result + i * 2; case 3: result = result + i * 3; } return result; }
举一反三
- 下面的方法,当参数值为2的时候返回值是多少public int getValue(int i) { int result = 0; switch (i) { case 1: result = result + i; case 2: result = result + i * 2; case 3: result = result + i * 3; } return result; } A: 10 B: 8 C: 6 D: 4 E: 2 F: 0
- 以下代码执行的结果是:( )int i=2;int result = 0;switch (i) {case 1:result = result + i;case 2:result = result + i * 2;case 3:result = result + i * 3;}System.out.println(result); A: 0 B: 2 C: 4 D: 10
- 下面程序段的输出结果是( )。 public class Test public static void main ( String[] args) int result=0; for ( int i=1;i<=5;i++) if ( i%2==0 ) continue; result + =i; System. out. println ("result is " + result ); A: result is 7 B: result is 8 C: result is 9 D: result is 10
- 下面程序段的输出结果是( )。 public class Test public static void main (String[] args) int n=10,result=0; for (int i=1;i<=n;i++) result+=i; System.out.println("result is"+result); A: A) result is 55 B: B) result is 45 C: C) result is 56 D: D) result is 54
- 把下面代码补全:计算10的阶乘并输出。[br][/br] int result = 1; for(int i = 2; i <= 10; i++){ } System.out.println(“result=”+ result);
