string objects are called immutable as once value has been assigned to a string, it can?t be changed and if changed, a new object is created.

In below example, reference str refers to a string object having value ?Value one?.


String str="Value One";
1
String str="Value One";


When a new value is assigned to it, a new String object gets created and the reference is moved to the new object.


str="New Value";
1
str="New Value";

    java does not support multiple inheritance because different classes may have different variable with same name that may be contradicted and can cause confusions resulting in errors.Java supports it through the interfaces.A class can extend one class and can implement more than one interfaces also.those interfaces may have variables with same names.Wont they create confusion?
