program runs, of course, can not find the corresponding class. The company compiled server is actually configured with multiple JDK versions, and Android compilation is the JDK version set when setting environment variables.Compiling android4.4 uses jdk1.6, and compiling android5.0 uses jdk1.7, which involves switching the JDK version at any time. First to see how to set the JDK environment variables, Baidu Search to get the answer is to modify the ~/.BASHRC or modify the/etc/profile file to co

Unpack first sudo tar zxvf./jdk-8u72-linux-x64.tar.gz Then use MV to move to the directory you want to reach, such as: MV jdk1.8.0_72 * * * * * (target location) 3. Setting Environment variables Edit the. bashrc file. Enter the following command at the terminal: Vim ~/.BASHRC At the end of the file, add the following lines of code: Export JAVA_HOME=XXX (JDK install

If there is more than one Java version installed (sometimes some software installed itself), how to easily switch it. In addition to the common settings environment variables, today learned a new way to switch:Update-alternatives--config JavaUpdate-alternatives--config JavacAlso, how to install your own Java version:sudo update-alternatives--install/usr/bin/java

kinds of links: Hard link (hard link) and soft link (also known as symbolic link, that is, soft link or symbolic link). Links for Linux systems to solve the shared use of files, but also brings the hidden file path, increase the security of permissions and save storage, and other benefits. If an inode number corresponds to multiple file names, these files are referred to as hard links. In other words, a hard link is one file that uses multiple aliases (the following figure hard link is an alias

You can use the LS command to see that Python binaries are available in your system as follows. $ ls/usr/bin/python* /usr/bin/python/usr/bin/python2/usr/bin/python2.7/usr/bin/python3/usr/bin/python3.4/ usr/bin/python3.4m/usr/bin/python3m Perform the following command to view the default Python version information: $ python--version python 2.7.8 1.

the top is modified to enumerate the edges to find D value, the complexity of O (N2). In fact, the complexity of the KM algorithm can be achieved O (N3). We give each y vertex a "slack" function slack, which is initialized to infinity each time we start looking for an augmented path. While looking for an augmented path, when checking for edges (i,j), if it is not in the equal sub-graph, let

Floyd-w is the shortest distance from any point to any point, because of the high complexity, so in order to only a point to any point of time to easily time out, the Dijkstra algorithm is to solve a point to any point of the distance problem, can be used for the direction of the graph or the graph, only need to pay attention to the initialization of the good, In the same way that the FLOYD-W algorithm uses the critical matrix to store the graph, we also need an array to store the origin (1) dis

In Ubuntu, if you have more than one Java version installed (sometimes some software installs itself), how can you easily switch?

When you install Debian Linux, the installation process may also provide you with multiple Python versions available, so there will be multiple Python executable binaries in the system. You can use the LS command to see that Python binaries are available in your system as follows. $ ls/usr/bin/python* /usr/bin/python /usr/bin/python2 /usr/bin/python2.7 /usr/bin/python3 / usr/bin/python3.4 /usr/bin/python3.4m /usr/bin/python3m Perform the following command to view the default Python vers
