How to calculate simple interest in java ?

[xanix]

Hi,
I am new to programming language. I recently started learning java language. Yesterday our sir has given us assignment in which one program is there like write program to calculate simple interest in java. I tried various method but I unable to write that program. That's why I asked this question on this forum. So if you have any idea about this please help me.Thanks in advanced.

Hi,
Rather than writing whole program I just give you logic behind it. You have to write that program on your own, this will help you solving other program quickly. You have to use following formula to calculate simple interest :

SimpleInterest=PrincipleAmount*RateOfInterest*NumberOfYears

In your program you have to take all three value from user then calculate it to get the Simple Interest.
I think this will help you.

I just given you esy program to calculate simple interest. Tried to comile it in your computer and let me know whether it works or not.

   
      int main()
  
      {

      int a,b,count1;
 
      float c,simp;

       
 
      count1=1;

      while(count1<=3)

      {
 
      printf("\n enter values of a,b,andc");

      scanf("%d %d %f",&a, &b, &c);

      simp=(float)a * (float)b * c / 100;

      printf("simple interest = %f rs.",simp);
  
      count1=count1+1;

      }
  
       

      return(0);

      }

This is program to calculate simple interest just go through it

public class SimpleInterest{


float princ,IR, NOY;

public void setPrincipal(float princ){
this.princ = princ;
}

public void setIntRate(float IR){
this.IR = IR;
}

public void setNumOfYears(float NOY){
this.NOY = NOY;
}

public float calculateSimpleInterest(){

return (this.princ * this.IR * this.NOY) /100;

}

public static void main(String argv[]){

float princ,IR, NOY;

SimpleInterest Obj1 = new SimpleInterest();

princ = Float.parseFloat(argv[0]);
IR = Float.parseFloat(argv[1]);
NOY = Float.parseFloat(argv[2]);

Obj1.setPrincipal(princ);
Obj1.setIntRate(IR);
Obj1.setNumOfYears(NOY);

System.out.println ("Principal amount = "+princ);
System.out.println (" Rate of interest = "+IR);
System.out.println ("Number of Years = "+NOY);

System.out.println ("Simple Interest Amount is = "+Obj1.calculateSimpleInterest());
}

}

I write program to calculate simple interest using some value try to understand each step.

class simpleInterest
{
public static void main(String args[])
{
float princ, noy, roy, simpleInt;
princ = 20000;
noy= 8;
roy = 9.3F;
simpleInt = princ * noy * roy ;
simpleInt = simpleInt / 100 ;
System.out.println("\n Simple Interest on a principle of "+princ+" is "+simpleInt+" at the rate of "+roy+" for a period of "+noy);

}
}

I think this is the simplest program to calculate simple interest.

import java.util.Scanner;
class simpleinterest
{
Scanner obj=new Scanner(System.in);
double pr,r,t,x,y,z;
void interest( double princ,double roi,double year)
{
y=(princ*roi*year)/100;
System.out.println("simple interest :"+y);
}
void interest(double princ, double roi,double year,int x) 
{
double d=year/x;
double l=1+(roi/100);
z=princ*(Math.pow(l,d)-1);
System.out.println("compound interest:"+z);
}
public static void main (String args[])
{
simpleinterest obj1=new simpleinterest();
simpleinterest obj2=new simpleinterest();
obj1.interest(200000,20,32);
obj2.interest(200000,20,32,7);
}
}

can we use
int long princ.=10,000????

[Janos™]

can we use
int long princ.=10,000????

If you have an int object, you should easily be able to convert that to a long and then the same number back to an int.

int x = 10000;
System.out.println(x); // 10000
long y = (long)x;
System.out.println(y); // 10000
int z = (int)y;
System.out.println(z); // 10000
