One of the Questions : BOOK K&B 6>PAGE 817

If the current directory is test, and you create a .jar file by invoking this,

A. Foo.java
B. Test.java
C. myApp/Foo.java
D. myApp/Bar.java
E. META-INF/Foo.java
F. META-INF/myApp/Foo.java
G. myApp/myAppSub/Bar.java

then which path names will find a file in the .jar file?

Why A is not correct ?


Tell the difficulties that i am difficult.

Why do you think that MyJar.jar hasn't Foo.java ?

no i'm not thinking that. myjar.jar has definitely got Foo in it. but just think what would be its hierarchy/directory structure in the jar file. if you can try jar -tf myjar.jar to see the structure of the jar. also look at the C option as well. by looking at the option , you can probably make out the difference.

this is what is difficult in exam . how much you can keep your cool and focus . believe me exam questions are not so tough. but we have to solve them with real exam pressure and all that stuff. good luck and good night
