if you need to install java in Ubuntu, you can try using following command and you will get oracle-java-installer in your synaptic package manager, click it and install it.
如果您需要在 Ubuntu 中安装 java，您可以尝试使用以下命令，您将在突触包管理器中获得 oracle-java-installer，单击并安装它。
sudo add-apt-repository ppa:webupd8team/java
Else try following steps
否则尝试以下步骤
$ wget http://download.oracle.com/otn-pub/java/jdk/6u34-b04/jre-6u34-linux-i586.bin
$ chmod u+x jre-6u34-linux-i586.bin
$ ./jre-6u34-linux-i586.bin
$ sudo mkdir -p /usr/lib/jvm
$ sudo mv jre1.6.0_34 /usr/lib/jvm/
$ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jre1.6.0_34/bin/java" 1
$ sudo update-alternatives --install "/usr/lib/mozilla/plugins/libjavaplugin.so" "mozilla-javaplugin.so" "/usr/lib/jvm/jre1.6.0_34/lib/i386/libnpjp2.so" 1
$ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jre1.6.0_34/bin/javaws" 1

The issue is that you have created a folder named "java" in /usr/bin . Remove the folder from /usr/bin and run the command again.
问题是您在 /usr/bin 中创建了一个名为“java”的文件夹。从 /usr/bin 中删除文件夹并再次运行该命令。

Instead of Step 4 :
4. mkdir -p /usr/lib/jvm /usr/bin/java /usr/bin/javac /usr/bin/javaws
而不是第 4 步：4。 mkdir -p /usr/lib/jvm /usr/bin/java /usr/bin/javac /usr/bin/javaws
Just use
只需使用
$mkdir -p /usr/lib/jvm
$mkdir -p /usr/lib/jvm
and make sure that you are moving the files to usr/lib/jvm , for that use
并确保您将文件移动到 usr/lib/jvm ，以便使用
$mv -v jre1.6.0_34 /usr/lib/jvm/
$mv -v jre1.6.0_34 /usr/lib/jvm/
so that you can see the details and after installation change the configuration of java and javaws by :
以便您可以查看详细信息，并在安装后通过以下方式更改 java 和 javaws 的配置：
$update-alternatives --config java
$update-alternatives --config java
select from the option similarly ,
类似地从选项中选择，
$update-alternatives --config javaws
$update-alternatives --config javaws
this should work if you have already another java installed
如果您已经安装了另一个 java，这应该可以工作
