Answer 1

Ans: - Here we are taking problem of Simple interest calculation for the given time period.

Simple Interest Definition: - Simple interest is a very common mathematical term which is used in banking sector to calculate the interest for a specified amount for specified amount of time period.

Mathematical Computations: - Simple Interest = (P × R × T)/100  

where P = Principal Amount, R = Annual interest rate, T = Time period or duration for the interest

Problem: - Write a Java program to find the simple interest for the given time period by using the given parameters i.e. principal amount for the interest and rate of the interest.

Pseudocode: -

//pseudocode to calculate the simple interest

Begin //start of the code

Define variables p, r, t, Simple_Interest // initialize variables

Read: p, r, t // input values p,r,t by the user

Compute Simple_Interest as (p*r*t)/100    // calculating simple interest using the formula

Print Simple_interest     // Display result on the screen

End   // end of the program

Code: -

Execute Share Source File STDIN 1 public class Interest 2 { 3 public static void main (String args[]) 4. float p, r, t, si; // P = Principal Amount, R = Annual interest rate, T = Time period 5 р 25000; r = 7; t = 5; s_i = (p*r*t)/100; 7 System.out.println("Simple Interest is: " +s_i); }}| { = 6 8

Output: -

1.II Result $javac Interest.java $java -Xmx128M -Xms 16M Interest Simple Interest is: 8750.0

There is decimal after the Output value because we have used the float datatype for defining the variables.
