How to configure the java environment? 1. Download jdk (http://java.sun.com/javase/downloads/index.jsp)
2. Install jdk-6u14-windows-i586.exe
3. Configure environment variables: Right-click my computer --> "advanced" --> "environment variables"
1) Create the JAVA_HOME variable value in the system variable: C: \ Program Files \ Java \ jdk1.6.0 _ 14 (set it according to your own installation path)
2) New classpath variable value:.; % JAVA_HOME % \ lib \ tools. jar
3) Add the variable value % JAVA_HOME % \ bin; % JAVA_HOME % \ jre \ bin to the path variable (separated)
4. Start --> Run --> input javac --> "Enter" to print the usage instructions. The configuration is successful.
Supplementary environment variable parsing:
JAVA_HOME: jdk installation path
Classpath: only the classpathjava command can be used to load the class path in java. "is added to the path to indicate the current path.
Path: The system recognizes java and javac commands in any path.
In software testing, the test environment is inconsistent with the actual deployment. How can I solve the configuration problem? Suitable for testing risks. Apply for the same environment
1. performance differences are much stronger than the user's machine's CPU memory.
2. for differences between other types of software and windows unix, pay special attention to the differences between different types of software.
Make sure to compare and test each software in sequence. The same software version number is the same.
Solution: apply for the same environment without conditions. Only the superior can be reported to let the superior understand the risks.
