Answer:
The program is given in the explanation section
Explanation:
import java.util.Scanner;
public class num5 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the three edges of the triangle");
double sideA = in.nextDouble();
double sideB = in.nextDouble();
double sideC = in.nextDouble();
if(sideA < sideB + sideC && sideB < sideA + sideC && sideC < sideA + sideB){
double perimeter = sideA+sideB+sideC;
System.out.println("perimeter: "+perimeter);
}
else{
System.out.println("Invalid inputs");
}
}
}
Three edges for a triangle :
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C. The length of the sides of a triangle may be the same or different. If all the 3 sides of a triangle are equal then it is an equilateral triangle.
The required codes are:
import java.io.*;import java.util.Scanner;class Perimter{public static void main(String args[]){ int a,b,c; a=0;b=0;c=0;Scanner sc=new Scanner(System.in);System.out.println("Enter side 1 value"); a=sc.nextInt(); System.out.println("Enter side 2 value"); b=sc.nextInt(); System.out.println("Enter side 3 value"); c=sc.nextInt(); int p=a+b+c; if((a+b&gt;=c)&amp;&amp;(a+c&gt;=b)&amp;&amp;(b+c&gt;=a)){ System.out.println("Permiter of the triangle"+p);} else{ System.out.println("Invalid Input"); }}}I have executed the code in the online compiler. Please execute it under the offline compiler.Input:122
