++++++++++++++++++++++++++ about strings ++++++++++++++++++++++++++ 1. someobject.getClass() returns Object.class eg String.class. 2. strings can be created by either ="somestring" or new String(). The latter returns an empty string. 3. the same string created with different references are no the same object. 4. you can concatenate strings by using + or by using StringBuilder and .append and .toString()... this is a better approach as it creates only the final string.
