i used jwitter4j. not contains packages classloader.java. can do? please help me.

how project set up? compiling , running command line or in ide? when have class named simplestream package com.crowley.simplestream; statement @ top, com.crowley.simplestream.simplestream qualified name of class. javac compiler emit .class file in current directory default, expects class found in com/crowley/simplestream/simplestream when run it.

normally maintain source com.crowley.simplestream.simplestream in file com/crowley/simplestream/simplestream.java in project, typically underneath src or src/main/java directory, , ide (such eclipse or idea) build source files in directory parallel output directory construction .class files. sounds may building command line, of course of study can do, must take business relationship qualified name of class , java expects find it.

for example, set source appropriate directory , type total path when invoking javac, or utilize -d switch javac tell set .class file, , utilize qualified name of class when running it:

java com.crowley.simplestream.simplestream

java
