Multiple inheritance is not possible with class, you can achieve it with the help of interface but not with class. It is by design of java language. Look a comment by James gosling.

by James Gosling in February 1995 gives an idea on why multiple inheritance is not supported in Java.

JAVA omits many rarely used, poorly understood, confusing features of C++ that in our experience bring more grief than benefit. This primarily consists of operator overloading (although it does have method overloading), multiple inheritance, and extensive automatic coercions.
