java jre 安装方法 FOR FEDORE
Let's begin by downloading the latest version of JRE (Java Runtime
Environment) from here
.
Just click on the Download link where it says Java Runtime
Environment (JRE) 5.0 Update
, then you�ll need to accept the license
and download the Linux self-extracting file
.By default, Fedora Core 6 systems come with an old
Java software installed, so you need to install a newer version of Java
Runtime Environment to enjoy all the Java applications out there. In
this quick guide, I will teach you how to update/install your Java
Environment.
WARNING:
Please remember to always replace the xx
from the jre-1_5_0_xx-linux-i586.bin
file with the latest version. At the moment of this guide�s writing,
the latest version was 09
, so the file should look like this: jre-1_5_0_09-linux-i586.bin
After
you have finished downloading the file, you need to move it into the /opt
folder. Open a console and type:
mv
jre-1_5_0_xx-linux-i586.bin /opt
Now, you will need to
make this file executable so you can extract it. Follow the commands
below:
cd /opt
- so you can go
into the /opt directory
chmod +x
jre-1_5_0_xx-linux-i586.bin
And now, let's run the
executable file with the following command:
./jre-1_5_0_xx-linux-i586.bin
You'll
be prompted with the License Agreement, hit space until you are asked
if you agree or not. Type Yes
and the extraction process will
begin. After the extraction process is finished, just remove the binary
file with the following command:
rm -rf
jre-1_5_0_xx-linux-i586.bin
Now, let's put the Java
plugin into your browser's plugin folder. Konqueror, Firefox and Mozilla
browsers will all look into the same folder, for plugins. So type the
following command:
ln -s
/opt/jre1.5.0_xx/plugin/i386/ns7/libjavaplugin_oji.so
/usr/lib/mozilla/plugins/libjavaplugin_oji.so
Well,
now you need to make the Java executable available for the whole system,
so you can run all the Java applic

1. 寄存器（register）。这是最快的存储区，因为它位于处理器内部。但你不能直接控制，也不能在程序中感觉到寄存器存在的任何迹象。
2. 堆栈（stack）。位于通用RAM中，堆栈指针若向下移动，则分配新的内存；若向上移动，则释放那些内存。这是一种快速有效的分配存储方法，仅次于寄存器。创建程序时候，JAVA编译器必须知� ......

Java中"异常机制"的深入研究
由于本文旨在探讨Java"异常机制"的深层原理，因此关于"异常"的使用方法都不做详细说明。首先看一段非常熟悉的用于打开一个文件的C程序段：
FILE *fp;
fp=fopen(filename,"rw");
if(fp==NULL){
printf("cannot open file\n");
exit(0);
}
