Lab 2 Solution

class IncDecOp { //start of class block

//Example to illustrate increment and decrement operators

public static void main(String [] args) { // start of method block

int a = 20, b = 0;

//Prints out initial values of a & b

System.out.println("a ="+ a + "b =" + b);

// Value of b is assigned the original value of a before the increment operation

b = a++;

System.out.println("a ="+ a + " b =" + b);

a = 20;

b = ++a;

System.out.println("a ="+ a + " b =" + b);

a = 20;

b = a--;

System.out.println("a ="+ a + " b =" + b);

a = 20;

b = --a;

System.out.println("a ="+ a + " b =" + b);

} //end of method block

} //end of class block

Values of a & b:

a =20 b =0

a =21 b =20

a =21 b =21

a =19 b =20

a =19 b =19

class Cast {

public static void main(String [] args) {

double a = 1.5;

int b = 2;

int c = (int) a*b; //Explicitly stating that you need the value to be

rounded to an int

System.out.println("c = "+ c);
