ReplyDeleteAny one can help me with this...Write a Menu driven program to find the area of an Equilateral triangle, an Isosceles triangle and a Scalene triangle as per the user’s choice....

ReplyDeleteHere, theres your answer :)

Deleteimport java.io.*;

public class triangle

{

public static void main(String args[]) throws IOException

{

InputStreamReader read = new InputStreamReader(System.in);

BufferedReader in = new BufferedReader(read);

int c;

float a,s,p,q,r,b;

double area;

System.out.println("1.Area of equilateral triangle");

System.out.println("2.Area of isosceles triangle");

c=Integer.parseInt(in.readLine());

switch(c)

{

case 1:

System.out.println("Enter side of an equilateral triangle");

s=Float.parseFloat(in.readLine());

area=Math.sqrt(3*s*s)/4;

System.out.println("Area="+area);

break;

case 2:

System.out.println("Enter the side and base of isosceles triangle");

a=Float.parseFloat(in.readLine());

b=Float.parseFloat(in.readLine());

area=b/4*(Math.sqrt(4*a*a-b*b));

System.out.println("Area="+area);

break;

default:

System.out.println("Wrong choice ");

}

}

}

hats off to such a basic conceptual program.. although little errors can be pointed out.

ReplyDeletePlease help me with this

ReplyDeleteWrite a Menu Driven Program To Accept two numbers and 2 Choices to choose whether the number is a Neon and a Palindrome

its urgent please help to slove this program:

ReplyDeletewrite a program to print the following pattern:

int i, j;

for (i=1;i <=10;i=i+2)

{

for (j=i;j>=1;j=j-2)

System.out.print(j);

}

System.out.println ();

}

}

}

No I ont want the output as 131531...

DeleteI want it as:

1

31

531

7531

97531

please write it so output comes in as in the gap of 1 line

Please ! help me with this program in blue j the simplest way without using buffered reader - ( i'm in 9th standered)

ReplyDeleteYou want to buy an old car from 'sale and purchase', where you can get a car in depreciated price . The depreciated value of a car is calculated on its showroom price and the number of years it has been used .The depreciated value of a car is calculated as per tariff given below

no. of yrs used rate of depreciation

1 10%

2 20%

3 30%

4 50%

above 4 60%

Write a menu driven program to input showroom price and the number of years used ('1' for 1yr old, '2' for 2yr old) and so on. Calculate the depreciated value. Display the original price of car , depreciated value and the amount paid for the car.
