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.

for (int i = 1; i <= 10; i++) {
System.out.print(a+ " ");
a=a+10;

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");
}
