77. Write a program in java to ask three sides of a triangle and determine whether a triangle can be formed or not.

class Triangle {
       public static void main(String[] args) {
       int side1 = 0;
       int side2 = 0;
       int side3 = 0;
       System.out.println("Enter three sides of a triangle: ");
       side1 = Integer.parseInt(System.console().readLine());
       side2 = Integer.parseInt(System.console().readLine());
       side3 = Integer.parseInt(System.console().readLine());

       if (side1 + side2 > side3 && side2 + side3 > side1 && side1 + side3 > side2) {
           System.out.println("Triangle can be formed");
       } else {
           System.out.println("Triangle cannot be formed");
       }
   }

}

78. Write a program in java to ask three sides of a triangle and determine whether a triangle is equilateral isosceles or scalene triangle or not.

       int side2 = 0;
       int side3 = 0;
       System.out.println("Enter three sides of a triangle: ");
       side1 = Integer.parseInt(System.console().readLine());
       side2 = Integer.parseInt(System.console().readLine());
       side3 = Integer.parseInt(System.console().readLine());

       if (side1 == side2 && side2 == side3) {
           System.out.println("Triangle is equilateral");
       } else if (side1 == side2 || side2 == side3 || side1 == side3) {
           System.out.println("Triangle is isosceles");

           a=a+10; 
       } 
   } 
}

80. Write a program to input any number and display whether it is odd or even.

class OddEven {
   public static void main(String[] args) {
       int num = 0;
       System.out.println("Enter a number: ");
       num = Integer.parseInt(System.console().readLine());

       if (num % 2 == 0) {
           System.out.println("Number is even");

       }
       else {
           System.out.println("Number is odd");
       }

   }

   }

81. Write a program to input any number and check whether the given no. is divisible by 5 or not.

class Divisible {
   public static void main(String[] args) {
       int num = 0;
       System.out.println("Enter a number: ");
       num = Integer.parseInt(System.console().readLine());

       if (num % 5 == 0) {
           System.out.println("Number is divisible by 5");
       } else {
           System.out.println("Number is not divisible by 5");
       }
   }
      
   }

82. Write a program in java to enter any 15 numbers and print only those numbers which are divisible by 5.

       int num = 0;
       int count = 0;
       int divisibleBy5 = 0;
