String o= ""; 24. z: 25. for(int x=0; x<3; x++){ 26. for(int y=0; y<2; y++){ 27. if(x == 1) break; 28. if(x==2 && y==1) break z; 29. o=o+x+ y; 30. } 31. } 32. (o); 33. } go() 方法被调用后,产生什么结果? 以下代码: 10. intx= 0; 11. inty= 10; 12. do{ 13. y--; 14. ++x; 15. }while(x < 5); 16. (x + "," + y); 运行结果是? 以下代码: 1. public class Breaker{ 2. static String o= ""; 3. public static void main(String[] args){ 4. z: =o+ 2; 6. for(int x=3; x<8; x++){ 7. if(x == 4) break; 8. if(x == 6) break z; =o+ x; 10. } 11. (o); 12. } 13. }运行结果是?以下代码: 1. public class Spock{ 2. public static void main(String[] args){ 3. Long tail = 2000L; 4. Long distance = 1999L; 5.
