Hello friends,

This is Kiran , once i encountered Question given below in a Mock Test for Java Fundamentals 2.
but i am not aware of the following question.


CLASSPATH=app3.jar;app1.jar;\lib\Sys.class
Given the above classpath, what is the first user defined place that the JVM will search for "com.foo.App1"?
Choice 1
app1.jar
Choice 2
\lib\Sys.class
Choice 3
app3.jar
Choice 4
%JAVA_HOME%\lib\core.jar
Choice 5
%JAVA_HOME%\lib\lib.jar

please reveal the criteria behind this. discuss the Class searchig & provide me if there are useful links ...

Thank you very much & waiting.

Obviously the first user-defined space where the JVM will search for classes is app3.jar.

Remember that both java and javac commands search some coommon places like...

1) %JAVA_HOME%/bin
2) %JAVA_HOME%/jre/lib/ext etc..... in a particular order

and then it searches the user-defined class paths...


1) the one which we give using set classpath and
2) the one which we give using java and javac command flag -cp (or) -classpath

and they search those directories in the order in which you specify them..... and hence the answer app3.jar
