Question

I have a java code where I want to use Guava libraries CharMatcher function. I downloaded it, but can’t able to add it to my existing code. Can anybody help me how to add that .jar file to the java code (step-by-step). I am using JDK 1.6. Thanks in advance.

I am using the following command:

And Used follwing code:

public class Test {

 public static void main(String[] args) {

try {

 String key = "hello";
 Multimap<String, Integer> myMap = HashMultimap.create();
 myMap.put(key, 1);
 myMap.put(key, 5000);
 System.out.println(myMap.get(key));

}

 catch (FileNotFoundException e) {
  System.out.println(e);
  } catch (Exception e) {
  System.out.println(e);
  }


}
}

I store Guava Library and Test.java in C:\Program Files\Java\jdk1.6.0_25\bin . Can anybody help me where is the problem because it is showing errors.

Suppose you are using Eclipse as IDE, here is the picture:

EDIT: if you don’t use any IDE, you just must use CLASSPATH variable:

javac -classpath path_to_your_jar/yourjar.jar your_code.java

‘-classpath’ or ‘-cp’ switch gives you possibility to tell javac where your libraries are located.
