Exercise 5 Write a Java program that computes the sum of two rational numbers given by the user.
[Note: If two numbers are rational, then we can write them in the formand for some
integer values of a, b, x and y, and x and y cannot be zero.
Then their sum is:
b
+
y
NA
bx
=
+
yx
(ay+bx)

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.
