Java Program to find if Triangle can be formed using given 3 sides

Algorithms – Java Program to find if Triangle can be formed using given 3 sides

Objective– Given 3 side lengths, write a program to find out if using these 3 sides, a triangle can be formed.

Example:

Triangle can be formed using side 2.5, 3.5, 5.0
Triangle cannot be formed using side 1.0, 3.0, 5.0
Sum of 1.0 and 3.0 is not > 5.0

Approach:

  • If sum of length of any two sides is strictly greater than the length of third side then triangle can be constructed, else we cannot construct a triangle.
  • Say sides lengths given are- a, b, c then to form a triangle, a+b>c and b+c>a, a+c>b. If any of the condition is not true, triangle cannot be formed.

Java Code:


Output:

Triangle can be formed using side 2.5, 3.5, 5.0
_____________________
Sum of 1.0 and 3.0 is not > 5.0
Triangle cannot be formed using side 1.0, 3.0, 5.0
