Hi all,

        So I am reading on Spring MVC and many times I saw the word Assert in the code. what exactly is this keyword? is it part of assertions? if Yes then where exactly assertions help and what is it.
        I have pasted the sample code from the book displaying Assert.
public Flight(List<FlightLeg> legs, BigDecimal totalCost) {
Assert.notNull(legs);
Assert.isTrue(legs.size() >= 1, "Flights must have at least one leg");

this.legs = legs;
this.totalCost = totalCost;
}
