【JAVA】配置JAVA环境变量,安装Eclipse

【JAVA】配置JAVA环境变量,安装Eclipse Java程序依赖JDK，就像C#程序依赖.NetFrameWork一样。 所以在开发之前，必须在win7或者是linux上，安装jdk(JavaDevelopkit)里面包括java一些工具，还有JRE(JavaRuntimeEnvironment)Java运行环境。 系统:windows7 jdk版本:jdk1.7 安装路径:c:/java 安装JDK时，上图显示的公共JRE和后续单独安装的JRE是一样的。所以只装一个就可以了。 coefficient not greater than 1.3; High efficiency: control 1 hour travel time between any two points within the various groups within the area up to half an hour, 1-hour access to the airport, 45min reached the city's main traffic hub, external highway for half an hour with the main channels connecting bus 1.5 hours between any two groups of core areas; Intensive: 2030 transit share rate of around 35%, 2050 bus sharing rate of 45% per cent. 3rd chapter, Yibin city, traffic situation and General ... 3.1.1 city traffic status 1, external transport passenger and cargo traffic in Yibin city, traffic at the present main railway, highway, waterway and air four modes of passenger and freight transport, thereand cultural heritage, highlighting the cultural taste and shape characteristics of the city in Yibin. According to forecasts, vision 2050 population will reach 2.1 million people in the center of Yibin city, urban land is around 210km2. Figure 2.6-1 2050 figure 2.7 land use planning in the Center City, Yibin city development requires the development of bus rapid transit construction and socio-economic development trends, Yibin city coordination, supporting urban space layout and infrastructure networks, transport organized, internal and external traffic hub smoothly linking, realizing sustainable development of Yibin city integrated transportation system. Concrete can be summarized as, accessible, efficient, intensive and sustainable.
