In Multiple Inheritance, Diamond problem may arise.
So Java supports multiple interface inheritance instaed of multiple inheritance.

Lets take an example

Class A{
public void clear(){

}
}

Class A{
public void clear(){

}
}

Class B extends A{
public void clear(){

}
}

Class C extends A{
public void clear(){

}
}

Now If multiple inhertence is allowed then

Class D extends B,C{ // 1 - It is not allowed
new D().clear(); // 2
}

In this case when we call statement 2 then it will we confusing to which clear method to be called. This type of problem is known as diamond problem
Thats why Java does not have multiple inhertence
