- 下面程序的输出为( )。 public class Test { public static void main (String args[]) { int x，y； x=1； y=2； System.out.println("The output is"+x+y)； } } A: The output is xy B: The output is 3 C: The output is 12 D: The output is x=1 y=2
- class Demo{ public static void main(String[] args){ int x = 0; try{ x = div(1,2); }catch(Exception e){ System.out.println(e); } System.out.println(x) ; } public static int div(int a,int b){ return a / b ; } }
- import java.io.IOException； public class ExceptionTest（ public static void main （String[]args） try （ methodA（）； ） catch （IOException e） （ system.out.printIn（“Caught IOException”）； ） catch （Exception e） （ system.out.printIn（“Caught Exception”）； ） ） public void methodA （） { throw new IOException （）； } What is the result？（） A: The code will not compile. B: The output is caught exception. C: The output is caught IOException. D: The program executes normally without printing a message.
