Sum of two number=3
public static void main(String[] args) {
int x = 0, y, z;
System.out.println("Enter two integers to calculate their sum");
Scanner in = new Scanner(System.in);
try {
x = in.nextInt();
} catch (InputMismatchException e ) {
System.out.print("INVALID");
}
y = in.nextInt();
z = x + y;
System.out.println("Sum of the integers = " + z);
}
