我是新來的java世界,並且一直在關注一些在線教程以開始。一切都很順利,程序編譯完美,然後突然間,沒有我看似改變任何東西,只要直接歸因於Eclipse的偏好,它就停止編譯任何代碼。即使簡單的Hello World代碼也不會編譯。所有我在控制檯線獲得的任何代碼是:在Eclipse中編譯任何java代碼時遇到問題
Usage: javaw [-options] class [args...]
(to execute a class)
or javaw [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-server to select the "server" VM
-hotspot is a synonym for the "server" VM [deprecated]
The default VM is server.
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A ; separated list of directories, JAR archives,
and ZIP archives to search for class files.
-D<name>=<value>
set a system property
-verbose[:class|gc|jni]
enable verbose output
-version print product version and exit
-version:<value>
require the specified version to run
-showversion print product version and continue
-jre-restrict-search | -no-jre-restrict-search
include/exclude user private JREs in the version search
-? -help print this help message
-X print help on non-standard options
-ea[:<packagename>...|:<classname>]
-enableassertions[:<packagename>...|:<classname>]
enable assertions with specified granularity
-da[:<packagename>...|:<classname>]
-disableassertions[:<packagename>...|:<classname>]
disable assertions with specified granularity
-esa | -enablesystemassertions
enable system assertions
-dsa | -disablesystemassertions
disable system assertions
-agentlib:<libname>[=<options>]
load native agent library <libname>, e.g. -agentlib:hprof
see also, -agentlib:jdwp=help and -agentlib:hprof=help
-agentpath:<pathname>[=<options>]
load native agent library by full pathname
-javaagent:<jarpath>[=<options>]
load Java programming language agent, see java.lang.instrument
-splash:<imagepath>
show splash screen with specified image

我不完全確定這是什麼或爲什麼它開始做它。我如何着手修復編譯器,以便繼續學習?
Eclipse的一個很好的教程,對於初學者是在http://www.vogella.de/articles/Eclipse/article.html。請執行上述步驟並檢查它是否有效。如果不是,那麼我們會弄清楚什麼可能是錯的。 – 2012-03-25 16:57:09
