#reccuring deposit #java #sourceCode #blueJ
This java console program helps you to calculate all the variables of reccuring deposit account chapter in class 9th Icse maths you can use this program to quickly calculate values of reccuring deposit or you can varify your's or maybe you can use it for your online exam.
//=========================================================
Source code:

import java.util.*;
class ReccuringDeposit{

// main method below.
public static void main(String args[]){
Scanner sc=new Scanner(System.in);
System.out.println("Welcome\nThis program helps u to calculate reccuring deposit values");

int m,p,r,n;
System.out.println("what do you want to calculate Princeple, maturity no., of months rate");
String ch;
ch=sc.nextLine();
switch(ch){
// rate calculation
case "rate" : System.out.println("enter priciple");
p=sc.nextInt();
System.out.println("enter no. of months");
n=sc.nextInt();
System.out.println("enter Maturity value");
m=sc.nextInt();
int y=(2400*(m-p*n))/(p*n*(n+1));
System.out.println("rate: "+y );
break;
//===============================================================================
//maturity calculation
case "maturity": System.out.println("enter rate");
r=sc.nextInt();
System.out.println("enter priciple");
p=sc.nextInt();
System.out.println("enter no. of months");
n=sc.nextInt();
int t=(p*n*(r*(n+1)+2400))/2400;
System.out.println("maturiy: "+t);
break;
//=============================================================================================
//principle calcution

case "principle":

System.out.println("enter rate");
r=sc.nextInt();
System.out.println("enter no. of months");
n=sc.nextInt();
System.out.println("enter Maturity value");
m=sc.nextInt();

int i=(2400*m)/(n*(r*(n+1)+2400));
System.out.println("Princple: "+i);
break;
//================================================================================================================
//months calculation
case "months": System.out.println("enter priciple");
p=sc.nextInt();
System.out.println("enter rate");
r=sc.nextInt();
System.out.println("enter Maturity value");
m=sc.nextInt();
double a=p*r;

double b=a+2400*p;

double c=-1*2400*m;

double d=Math.sqrt(b*b-4*a*c);

double a2=2*a;
double db=d-b;
double x1=db/a2;
double x2=(-b-d)/a2;
System.out.println("no. of months: x1="+x1+"\nx2: "+x2);
break;

default : System.out.println("Wrong choice");
}
}
}

//=========================================================
to use this program simply copy and paste this program in editor like bluej or simple editor.
then for blueJ click on void main.... to run it
for calculation of variables
write the name of it same as written in source code then write other values.
