heshuzhen1931

Linux下安装JDK1.6并且运行java程序和java项目例子

软件：jdk-6u13-linux-i586-rpm.bin
启动Linux系统，创建放软件的目录/usr/local/heshuzhen：
[root@localhost ~]# mkdir -p /usr/local/heshuzhen
把jdk-6u13-linux-i586-rpm.bin放到Linux下的/usr/local/heshuzhen目录下，
运行软件jdk-6u13-linux-i586-rpm.bin
[root@localhost ~]# cd /usr/local/heshuzhen/
[root@localhost heshuzhen]#chmod 777 jdk-6u13-linux-i586-rpm.bin
[root@localhost heshuzhen]#./ jdk-6u13-linux-i586-rpm.bin
如出现停顿按空格
如出现下列提示
Do you agree to the above license terms? [yes or no]
输入yes
[root@localhost heshuzhen]# rpm -Uvh jdk-6u13-linux-i586.rpm
[root@localhost heshuzhen]# vi /etc/profile（以下是该文件修成了的地方）
Profile文件中的内容如下：其中红色的部分是新添加的配置
# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

pathmunge () {

if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then

if [ "$2" = "after" ] ; then

PATH=$PATH:$1

else

PATH=$1:$PATH

fi

fi
}

# Path manipulation
if [ `id -u` = 0 ]; then

pathmunge /sbin

pathmunge /usr/sbin

pathmunge /usr/local/sbin
fi

pathmunge /usr/X11R6/bin after

for i in /etc/profile.d/*.sh ; do

if [ -r "$i" ]; then

unset i
unset pathmunge
#这里要注意，你要根据自己的安装的路径来写

1、测试jdk是否安装成功
[root@localhost FtpClient]# java -version
java version "1.4.2"
gcj (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2)

2、可以写一个简单的java程序进行测试：
[root@localhost heshuzhen]# vi A.java

类名：A.java
public class A
{

public static void main(String args[])

{


System.out.println("Hello World！");

}
}

编译程序：
[root@localhost heshuzhen]# javac A.java

运行程序：
[root@localhost heshuzhen]# java A
