先下载了个jdk-6u5-linux-i586-rpm.bin
照着网上说的用root用户执行了
chmod +x jdk-6u5-linux-i586-rpm.bin //所有用户可以执行
sudo ./jdk-6u5-linux-i586-rpm.bin //执行
结果输出:

鉴于我是个新新新手看不懂什么意思，只好从网上找了半天，结果发现原来debian和ubuntu一般用.deb安装软件，不用.rpm来安装packages。
那么就需要按照下列步骤来安装了：
1：./jdk-6u5-linux-i586-rpm.bin -x //生成好多个.rpm安装包
2：alien --scripts --keep-version -d *.rpm //把多个.rpm包转化为多个.deb包
3：dpkg -i *.deb //安装多个.deb包
4：删除你认为不重要的文件
然后看了看 /usr 下真的有一个 java目录了，该设置环境变量了：
1：vi /etc/profile //打开 /etc/profile 文件
2：在文件最后写入
JAVA_HOME=/opt/jdk-1.5.0_04
CLASSPATH=.:＄JAVA_HOME/lib.tools.jar
PATH=＄JAVA_HOME/bin:＄PATH
export JAVA_HOME CLASSPATH PATH
