It's not in your path.
它不在你的道路上。
use
利用
export PATH=$PATH:/usr/local/jdk/jdk1.5.0_10/bin
export JAVA_HOME=/usr/local/jdk/jdk1.5.0_10
Look at ~/.bash_profile for where to define this permanatly.
查看 ~/.bash_profile 在哪里永久定义它。

Must be in local path of java before running to see what version is installed. Use find / -name java?(this will list anything with java on the server copy the path ). path should end with..../jre/bin/java copy full path.
运行之前必须在java的本地路径下才能看到安装了什么版本。使用 find / -name java?（这将列出服务器上带有 java 的任何内容复制路径）。路径应以..../jre/bin/java 复制完整路径结尾。
Open Java location of the path you copied above, remove java at the end you path then enter,
Enter command below:
./Java -Version
打开上面复制的路径的Java位置，删除路径末尾的java然后输入，在下面输入命令：
./Java -Version
