+Q. Java Program for compound interest
+
+
+Formula to calculate compound interest annually is given by:
+
+Compound Interest = P(1 + R/100)r
+Where,
+P is principle amount
+R is the rate and
+T is the time span
+
+
+Input : Principle (amount): 1200
+        Time: 2
+        Rate: 5.4
+Output : Compound Interest = 1333.099243

+Q. Java Program for simple interest
+
+Simple interest formula is given by:
+Simple Interest = (P x T x R)/100
+Where,
+P is the principle amount
+T is the time and
+R is the rate
+
+
+EXAMPLE1:
+Input : P = 10000
+        R = 5
+        T = 5
+Output :2500
+We need to find simple interest on 
+Rs. 10, 000 at the rate of 5% for 5 
+units of time.
+
+EXAMPLE2:
+Input : P = 3000
+        R = 7
+        T = 1
+Output :210
