debian - Yet another "Could not find or load main class package" Java error -


i have bunch of java source codes git repository: https://github.com/kevin-wayne/algs4/

i extracted ~/java. after extraction, .java files in ~/java/algs4-master/src/main/java/edu/princeton/cs/algs4. cd'd said directory , compiled binarysearch.java class following instructions inside source code itself: javac in.java stdin.java out.java stdout.java binarysearch.java, completed without error , produced 5 java .class files.

however, running java edu.princeton.cs.algs4.binarysearch fails error: not find or load main class edu.princeton.cs.algs4.binarysearch. i'm $classpath correct: /home/larssend/java/algs4-master/src/main/java/edu/princeton/cs/algs4

my system debian testing openjdk 8 headless.

what should run compiled class files?

this offending java source code, in case it's needed:

java edu.princeton.cs.algs4.binarysearch

the jvm binarysearch class in edu.princeton.cs.algs4 package, maps edu/princeton/cs/algs4 starting directories in classpath. classpath should /home/larssend/java/algs4-master/src/main/java instead; way jvm find class in /home/larssend/java/algs4-master/src/main/java/edu/princeton/cs/algs4.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -
