Answer Posted / sushila sonare

in java only one super class should be there. If we are
saying multiple inheritance there is more then one super
class and at time of object creation super(){super calling
statement} statement is invoked and control goes to super
class but if we are saying multiple inheritance then there
is more than one super class so JVM getting confused,
control goes to where. So avoiding this confusion only
single inheritance are allowed in JAVA you can use this
concepts in multiple levels.

In interface compiler is not keeping default constructor, so
there is no constructor chain. Thats why we can have
multiple interface at same level.
