Unary operators in java with example Unary operator needs only one operand to increment, decrement, etc. Here are various unary operators, logical complement operator (!): reverses logical state or value of operand. If the value is false, it converts value to true and vice versa. unary minus…

Multiple inheritance in java Multiple inheritance is one of the object oriented feature where a class or a sub class can inherit features from more than one parent class or super class. But here problem occurs when methods with same signature exist in both parent class and child class.…

It can be implemented by any custom class and is found in java.lang package. Declaration: public interface Comparable<T> Parameters: <T> the type of objects that this object may be compared to Comparable interface…

Syntax: @FunctionalInterface interface interfacename { // one abstract method } NOTE: @FunctionalInterface is an annotation. This annotation is optional. Before Java 8 an interface had abstract method signature but didn’t define…
