1. Given:

1. public class returnIt {

2. returnType methodA(byte x, double y){ 3. return (short) x/y * 2; 4. 5. }

What is the valid returnType for methodA in line 2? A. B. C. D. E. F.

int byte long short float double }

Answer F

注释 :short 类型的 x,除以 double 类型的 y,再乘 int 的 2,所以结果是 第三行的强制转换,只是转换了 2.

1) class Super{

2) public float getNum(){return 3.0f;} 3) } 4)

5) public class Sub extends Super{

7) }

which method, placed at line 6, will cause a compiler error? A. public float getNum(){return 4.0f;} B. public void getNum(){} C. public void getNum(double d){}

D. public double getNum(float d){return 4.0d;} Answer :B

注意这道题主要考的是方法的

overload 和 override 。对于 overload,只有参数列表不同,才

B 错在方法名相同,但只有返

做为标准,而返回值和访问控制关键字不能做为标准,所以

x。

double 类型的。注意

6)

回值不同,这是错的。 C 和 D 是正确的 overload。对于 override ,则访问控制关键字只能更加公有化, 异常只能是超类方法抛出的异常的子类,也可以不抛出。返回类型,参数列表必须精确匹配。所以 A 是正确的 override 。

3.

1)public class Foo{ 2)

public static void main(String args[]){

3) 4) 5) 6)

try{return;}

finally{ System.out.println(\"Finally\");} } }

what is the result?

A. The program runs and prints nothing. B. The program runs and prints

“ Finally ”.

C. The code compiles, but an exception is thrown at runtime. D. The code will not compile because the catch block is missing. Answer:b

try......catch......finally 的问题。程序中如果遇到 语句都不执行,整个程序退出,还执行什么呀。 4.

1) public class Test{

2) public static String output=\"\"; 3) public static void foo(int i){ 4) 5) 6) 7) 8) 9) 10) 11) 12) 13) 14) 15) 16)

}

output+=\"4\";

17) 18) }

19) public static void main(String args[]){ 20) 21) 22) 23) 24) }

return ,则 finally 块先被执行,然后再执行

System.exit(1) ,则 finally 块及其后的

retrun,而 finally 块后面的语句将不被执行。如果遇到

try {

if(i==1){

throw new Exception();

}

output +=\"1\"; }

catch(Exception e){

output+=\"2\"; return; }

finally{

output+=\"3\";

foo(0); foo(1);

try......catch......finally 的问题。程序中如果遇到 语句都不执行,整个程序退出,还执行什么呀。 4.

1) public class Test{

2) public static String output=\"\"; 3) public static void foo(int i){ 4) 5) 6) 7) 8) 9) 10) 11) 12) 13) 14) 15) 16)

}

output+=\"4\";

17) 18) }

19) public static void main(String args[]){ 20) 21) 22) 23) 24) }

return ,则 finally 块先被执行,然后再执行

System.exit(1) ,则 finally 块及其后的

retrun,而 finally 块后面的语句将不被执行。如果遇到

try {

if(i==1){

throw new Exception();

}

output +=\"1\"; }

catch(Exception e){

output+=\"2\"; return; }

finally{

output+=\"3\";

foo(0); foo(1);

}

what is the value of output at line 22?

Asnwer:13423

3) 4) 5) 6)

try{return;}

finally{ System.out.println(\"Finally\");} } }

what is the result?

A. The program runs and prints nothing. B. The program runs and prints

“ Finally ”.

C. The code compiles, but an exception is thrown at runtime. D. The code will not compile because the catch block is missing. Answer:b
