Java assert

assert  logical_expresion;

assert  logical_expresion: string_expresion;

example:

if(daysInMonth == 30){

System.out.println("Month is April, June, September, or November");

} else if(daysInMonth == 31){

System.out.println("Month is January, March, May, July, August, October, or December.");

} else{

assert daysInMonth == 28 or daysInMonth == 29

System.out.println("Month is Februay");

}

else if(daysInMonth == 28 or daysInMonth == 29){

System.out.println("Month is February");

}else{

assert false;

//or assert false: "daysInMonth has the value" + daysInMonth;

}

Above two sections in different colur are two different ways to fullfill the same function else satement.
