So I have like 20 errors in here can someone tell me what I did wrong or how I can fix them?
I'm trying to write a program to get the area and perimeter of a triangle.
import java.util.*;
public class myTriangle3 {
//Declarations
static double area;
static double perimeter;
static double side1, side2, side3;
//******************************
//Main
//******************************
public static void main (String [] args) {
readData();
calculations();
printOutput();
printHeader();
printFooter();
}
//******************************
//readData
//******************************
public static void readData(){
System.out.print ("Enter side 1:");
side1 = scan.nextDouble();
a = side1;
System.out.print ("Enter side 2:");
side2 = scan.nextDouble();
b = side2;
System.out.print ("Enter side 3:");
side3 = scan.nextDouble();
c = side3;
s = perimeter/2.0;
}
//******************************
//calculate
//******************************
public static void calculations(){
area = Math.sqrt((s) * (s-a) * (s-b) * (s-c));
perimeter = a + b + c;
}
//******************************
//printHeader
//******************************
public static void printHeader(){
System.out.println("\n**********************");
System.out.println(" Jason Johnson");
System.out.println(" CS 1301B");
System.out.println(" 9/5/2014");
System.out.println("***********************");
}
//******************************
//printOutput
//******************************
public static void printOutput(){
printHeader();
System.out.println("Side1 is:" + side1);
System.out.println("Side2 is:" + side2);
System.out.println("Side3 is:" + side3);
System.out.println("Area is:" + area);
System.out.println("Perimeter is:" + perimeter);
printFooter();
}
//******************************
//printFooter
//******************************
public static void printFooter(){
System.out.println("****************** End of Report ********************");
System.out.println("****************** Have a good day ********************");
}
}
