请阅读程序,然后写出程序运行结果。public class Demo7 {p...ut.println(sum);}}
举一反三
- (10-6)请阅读程序,然后写出程序运行结果。public class Dem...(msg).matches();}}
- 请阅读程序,然后写出程序运行结果。 public class Demo7 { public static void main(String[] args) { int [] arr= new int[5]; int sum=0; Arrays.fill(arr, 3); for(int x:arr) { sum=sum+x; } System.out.println(sum); } }
- (2-6)请写出下面程序运行结果。public class Demo {pu....out.println(b);}}
- (2-6)请写出下面程序运行结果。 public class Demo { public static void main(String[] args) { int b = 011001; System.out.println(b); } }
- 请阅读下面的程序public class Demo { public static int sum(int a, int b) { return a + b; } public static float sum(int a, ____ b) { _____ a + b; }}
