where synchronization needed?

public class sample1
{
    private static Map m = new HashMap();
    //....
    //.....
    //
    public void fun(String str1, String str2, sample2 s )
    {
        String str = str1 + str2 + s.getName();
        String value = m.get(str);
    }
}

public class sample2
{
    private String name;
            // ......
            // ........
            pubic String getName()
             {
                  return name;
             }
}

Here my question is where exactly the variables (arguments of function fun) like str1, str2 and s (sample2 object) are stored, in heap or stack?

You will never have any synchronization failure with str1 and str2, because those variables are strings, and the string class is immutable in Java.
