Linux using a method from a jar file (Java Code)

Question

I am trying to write a program that prints out a statement through Linux. The catch is that most of the statement must come from a method from a jar file. Basically. my code looks like this

public class identification {
     public static void main(String[] args){ // Main method with print statement
          System.out.print("I am " + person()); 
    } 
}

The person() method comes from the jar file. It should give something like "I am bob on a computer," but I can't quite figure out how to set up the CLASSPATH environment variable in the .bash_profile so it reads the method from the jar file. Any ideas? I am sure this is a simple task.

Thank you for your time.

Answer 1

use cp command to add a jar file

java -cp lib/myJar.jar myPackage.Program

also I believe you may need to import class where method person is in. I don't know how your hierarchy is so I can't help you with that.

您可以像这样在您的类路径中添加一个jar：

export CLASSPATH=$CLASSPATH:/path/to/your/myJar.jar
