Hi friend,


const
A keyword in C++ that lets you freeze the value of a reference or of the fields in an object. There is no direct equivalent in Java. Java has the final keyword and the concept of immutable Objects.

volatile :
It is used on variables that may be changes simultaneously by other threads.
It is used in variable declarations that specifies that the variable is modified asynchronously by concurrently running threads.
It is used on variables that may be modified simultaneously by other threads.This warns the compiler to fetch them fresh each time,
rather than caching them in registers

assert :

An assertion checks a boolean-typed expression that must be true during program runtime execution.

Assertion statements have two forms as given below

assert expression;

assert expression1 : expression2;

For example :

assert value > 5 ;

assert balance > 0;

assert isCondition();


transient :

The transient keyword is used to indicate that the member variable should not be serialized
when the class instance containing that transient variable is needed to be serialized.

public class Class1{
private transient String password;
}


instanceOf :

class Parent {
public Parent() {

}
}

class Child extends Parent {
public Child() {
super();
}
}

public class MainExample{
public static void main(String[] a) {

Child child = new Child();
if (child instanceof Parent) {
System.out.println("true");
}

}

}
