Check the status of "VMware Network Adapter VMnet8" in Network and Sharing Center
192.168.255.1 是虛擬路由器為Windows分配的地址 192.168.255.2 是虛擬路由器的網(wǎng)關地址
Then, in centos, enter the command "vi /etc/sysconfig/network-script/ifcfg-eth0" to modify the eth0 information, and press the "insert" key to modify it
Modify information:
ONBOOT=yes BOOTPROTO=static
Add information:

The main difference between Java and other programming languages ??is its cross-platform feature of "writing at once, running everywhere". 1. The syntax of Java is close to C, but it removes pointer operations that are prone to errors, making it suitable for large enterprise applications. 2. Compared with Python, Java has more advantages in performance and large-scale data processing. The cross-platform advantage of Java stems from the Java virtual machine (JVM), which can run the same bytecode on different platforms, simplifying development and deployment, but be careful to avoid using platform-specific APIs to maintain cross-platformity.
