我正在使用Netbeans作为我首选的IDE。我不知道为什么会出现这样的问题，但是在安装Ubuntu 14.04 LTS时，我用来设置参数，然后安装JDK（1.8_u20）和Netbeans。
sudo mkdir -p /usr/lib/jvm
sudo tar -xzf jdk...tar.gz -C /usr/lib/jvm
sudo ln -s /usr/lib/jvm/jdk... /opt/jdk
然后我使用gedit ~/.bashrc来设置PATH变量。即
JAVA_HOME=/opt/jdk
JRE_HOME=$JAVA_HOME/jre
PATH=$JAVA_HOME/bin:$PATH
关闭gedit后，运行：
source ~/.bashrc
使用java --version测试java安装，通常应该输出JavaVirtualMachine（JVM）版本信息。例如：
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) Server VM (build 25.20-b23, mixed mode)
Netbeans安装可以通过...
完成./netbeans8.0.sh
或
./netbeans8.0.sh --javahome=/opt/jdk
我用来安装我的IDE但是上次我重新安装Ubuntu 14.04 LTS时，看起来用来表示interfaces, abstract classes, enum and so on的图标不起作用。在这个地方，它使用类图标。这对我来说非常困惑，因为眼睛无法帮助我确定文件内容。
请问如何解决。感谢。
