I have a compiled project in a jar file and I need to call a method from it.How can I do that in ubuntu terminal?
回答1:
You can not call any method from terminal or cmd of any class.
You can execute class through terminal.
If your jar is executable try: java -jar "Name of your Jar"
Or set the class path of your jar: java -classpath path-to-jar <package>.<classname>
回答2:
java -cp path/to/jar <package>.<classname>
example:
java -cp test.jar org.dekz.HelloWorld

This is not very specific statement. if you are interested to call main method of your Main class then you can do
java -jar path/to/yourjar/yourJar.jar
- JAR Basics
if you want to call a method from this class from another class then you need to add this jar into your classpath and then you can access other methods. but since you wrote from terminal I assume the first approach fits for you
回答4:
you can call a specific method from a jar file if and only if the developer programmed the file to call it from outside. You can use a jar explorer to fine the details of each class inside a jar file
