interface Altitude { //insert code here } 和4个声明: int HIGH = 7; public int HIGH = 7; abstract int HIGH = 7; interface int HIGH = 7; 分别插入到第2行,有多少行可以编译?()
1. class A implements Runnable ( 2. int i; 3. public void run ( ) ( 4. try ( 5. thread.sleep(5000); 6. i= 10; 7. ) catch(InterruptedException e) {} 8. ) 9. ) 10. 11. public class Test { 12. public static void main (string args[]) ( 13. try ( 14. A a = new A ( ); 15. Thread t = new Thread (a); 16. t.start( ); 17. 18. int j= a.i; 19. 20. ) catch (Exception e) {} 21. ) 22. } Which statement al line 17 will ensure that j=10 at line 19?()
int index = 1; String test = new String; String foo = test[index]; What is the result?()
1. public class Target { 2. private int i = 0; 3. public int addOne() { 4. return ++i; 5. } 6. } And: 1. public class Client { 2. public static void main(String[] args) { 3. System.out.println(new Target().addOne()); 4. } 5. } Which change can you make to Target without affecting Client?()
int [] my_Array; My_Array=new int [5]; For(int count = 0 ; count <=5; count ++) System.out.pringtln(my_Array[count]); 以上Java代码运行的结果是()
inta[10][10],已知a=1000,sizeof(int)=2,求a[3][3]地址()
