    # rpm -qa|grep jdk  查看JDK或者使用java -version
    # rpm -qa | grep gcj 查看gcj的版本
    # yum -y remove java-1.4.2-gcj-compat     （java-1.4.2-gcj-compa为查到的具体的gcj） 
2、安装jdk
     ①jdk-1_5_0_14-linux-i586-rpm.bin文件安装
         # chmod 777 jdk-1_5_0_14-linux-i586-rpm.bin     修改为可执行
         # ./jdk-1_5_0_14-linux-i586-rpm.bin              
         # rpm -ivh jdk-1_5_0_14-linux-i586.rpm         
     ②jdk-1_5_0_14-linux-i586.bin文件安装
         # chmod a+x jdk-1_5_0_14-linux-i586.bin         ← 使当前用户拥有执行权限
         # ./jdk-1_5_0_14-linux-i586.bin           
3、配置环境
    <1>#gedit /etc/profile
    <2>在最后加入以下几行：
       export JAVA_HOME=/home/yz    (这个路径为安装的路径)
           export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
           export PATH=$PATH:$JAVA_HOME/bin
    <3>#source /etc/profile     使配置生效
