第1题：
下面程序的输出结果是( )。 public class Sun { public static void main(String args[ ]) { int i = 1; switch (i) { case 0: System.out.println("zero"); break; case 1: System.out.println("one"); case 2; System.out.println("two"); default: System.out.println("default"); } } }
A．one
B．one，default
C．one，two，default
D．default
正确答案：C
解析：该题考查对switch-case-break的理解。每个分支语句后面必须有break语句，否则程序向下执行，直到遇到break语句或程序结束。所以，该题i=1时执行case1分支语句，而case1分支语句后没有break语句，程序继续向下执行case2分支语句和 default分支语句。A只执行了case 1；B只执行了case 1和default;C；只执行了default。故本题的正确答案是C。 -
