Inheritance:

The concept of getting properties of one class object to another class object is known as inheritance.
Here properties means variable and methods.

Types of Inheritance:

Multiple inheritance.
Multilevel inheritance.

Multiple inheritance:

The concept of Getting the properties from multiple class objects to sub class object with same priorities is known as multiple inheritance.
Java Doesn't Support multiple Inheritance.

Diamond problem:

In multiple inheritance there is every chance of multiple properties of multiple objects with the same name available to the sub class object with same priorities leads for the ambiguity.

//Multiple inheritance program
Class A{
}
Class B extends A{
public void show(){
}
}
Class C extends A{
public void show(){
}
}
Class D extends B,C{ // not supported by java leads to syntax error.
}

Why multiple inheritanc eis not possible in java

We have two classes B and c which are inheriting A class properties.
Here Class D inheriting B class and C class So properties present in those classes will be available in java.
