Calculate Area of triangle with 3 sides given using Java
<![CDATA[ import java.util.Scanner;
class AreaOfTriangle
{
public static void main(String args[])
{
Scanner sc= new Scanner(System.in);
System.out.println("Enter the 1st side of triangle:");
int a= sc.nextInt();
System.out.println("Enter the 2nd side of triangle:");
int b= sc.nextInt();
System.out.println("Enter the 3rd side of triangle:");
int c= sc.nextInt();
if((a+b)>c && (a+c)>b && (b+c)>a)
{
int s=(a+b+c)/2;
double area=Math.sqrt(s*(s-a)*(s-b)*(s-c));
System.out.println("Area of Triangle is: " + area);
}
else
System.out.println("Area of Triangle not exit");
}
}

Output
<![CDATA[C:\Users\SK\Desktop\javaPrograms>java AreaOfTriangle
Enter the 1st side of triangle: 20
Enter the 2nd side of triangle: 30
Enter the 3rd side of triangle: 40
Area of Triangle is: 290.4737509655563]]>
